We now reached midweek and there has not been much new going on in the volcano world, but some earthquakes happened. One of which was really close to a volcano.

Michael Ross informed us that he had a tweet saying something seems to be going on under Miyakejima volcano in Japan? Earthquake swarm in last 3 hours M2.9, 3.2, 4.7, 4.1, 3.0, 3.0, 4.6, 4.4 per JMA

Diana and others immediately started trying to find information on this volcanic island. http://staff.aist.go.jp/a.tomiya/miyakeE.html “A human view of an amazing community living on the edge of a lethal time bomb.. This Island is not a place you would expect to find “happy dancing natives” WRONG!
http://all-that-is-interesting.com/the-town-where-everyone-wears-a-gas-mask Hats off to the Japanese Tourism industry and government bodies who have, like Iceland and other Volcanic areas, utilised the danger, the beauty and the power and turned potential disaster into a lucrative industry for the locals. Authorities of El Hierro take note! Here is the most brilliant piece of advertising copy ever. It turns around the images and real threat of death and destruction and encourages would be holidaymakers that this is the ideal place for a Vacation of all vacations. It looks beautiful…….. Please read all 3 sections……” ( Thanks Diana Barnes)

There was a 5+ earthquake close to the volcano. GFZ has it as 5.6
An of course Earth Quake Report covers this event too! GVP on Miyakejima

Earth Quake Report on the Iran- Pakistan quake.
Iran has a rocky, mountainous soil, while the hard hit Pakistan region is built on a dry lake. That may be the reason why there are more victims to mourn in Pakistan.
Earthquake Report is attributing the death toll in Pakistan to building on lake sediment: http://earthquake-report.com/2013/04/16/massive-earthquake-iran-pakistan-border-region-on-april-16-2013/
From BBC news website. “Tuesday’s earthquake was about 180 times stronger in energy release than a 6.3-magnitude quake that struck on 10 April near the nuclear plant at Bushehr in south-western Iran. That quake killed at least 37 people and wounded 850.” http://www.bbc.co.uk/news/world-middle-east-22168202

Thank you Spica. I like these mid week summaries when there is a fair bit of global activity. It helps me to focus. and I can find links quickly without having to hunt through all the comments ( Me being lazy!)
Yes, thank you, interesting summary.
Only the gas masks in this “All that is interesting” blog-post seem from another time and part of the world, the second photo anyway looks like World War I scenes! And the second photo with masks looks like a staged event.
For comparison: http://commons.wikimedia.org/wiki/File:US_WWI_Gas_mask_with_bag.JPG
Saw some new ones not too long ago in Iceland, they looked totally different (also more sophisticated ones, not only the normal hospital masks).
The tourism advertisments are interesting, hm … 🙂
just came across this one at about using drones for volcano research on Manfred’s blog http://elhierro1.blogspot.com.au/

Nice round-up Spica – thanks.
For the UK-based fans of doom there is a programme on BBC2 tomorrow 9pm entitled “Could We Survive a Mega-Tsunami?”.
Looks like fairly regulation stuff: Canaries falling into the sea etc etc
No
Etna is not erupting big time.
Some clouds appear red in the setting sun. Smoke drifts upwars from the new southeast crater which is almost as high as the old one.
I just wanted to share this beautiful screenshot.
That IS beautiful . Thanks Spica.
Yes, many thanks Spica for the photo and the update.
Thank you Spica for the nice summary!
I am back from a short trip collecting glacial erratic boulders at the Baltic sea, some of which may even be lava 🙂 ….unfortunately I also had to attend some work related seminars during enticing sunshine.
@dfm. Just noticed a link you left on the last post on the 15th to some videos about seismic signatures. Very many thanks for that!!! I found it really interesting, especially the one of the rockfall as I wondered if that is what is shown on the El Hierro tremor chart at 04:22 today.
http://www.ign.es/ign/head/volcaSenalesDiasAnterioresHora.do?nombreFichero=CHIE_2013-04-17_04-05&estacion=CHIE&Anio=2013&Mes=04&Dia=17&tipo=1&hora=04-05
It certainly isn’t listed as a quake and yet is the biggest seismic signature showing for today. Don’t think it is a nearby running Elk though. 😀
Oops, also just noticed Spica reposted the link above. Many thanks Spica. Will this be put into Gems as I would love to refer to it from time to time and have such a long list of bookmarks now that I keep losing them? 😦
Hi Newby.
Yes I’ve seen this one. It shows nothing on the other islands sismos. so it is not a external quake. It seems like a rockfall to me. IT is interesting to compare the different graphs. It seems now that CHIE may be used to detect rockfalls.
Also noticed there was another small quake close to Hekla area again today. Almost in the same place as the two small quakes there yesterday. Not sure if this is really connected to hekla though of the nearby seismic zone.
I saw that too. It is at the border between the SISZ (South Iceland Seismic Zone) and Hekla volcanic system. 🙂
Rofl I imagine all deep down there, the Magmatic Trolls, Heklatites and SISZtites engaged in a Tug O’War. Now and then they take to being all shook up by some foreign and far reaching tremor, only to quickly re-group and pull and tug once more……….
Remember VC’s beginnings and the Saga of the Meaty Hat and the wildly abandoned dancing that was planned?
This is our Roots calling………..
this is one of my favorite pieces, this recording is great thanks Diana
Very fitting, thank you, Diana. 😆
In 2006, there were registered on the a.m. Miyakejima vocano no less than 100.000 earthquakes in about 2 months, incl. 5 over magn. 6: http://commons.wikimedia.org/wiki/File:US_WWI_Gas_mask_with_bag.JPG Which is a record even for Japan!
Sheesh! Inge, and they think they have it tough on El Hierro?
The link should of course have been another: http://sciencelinks.jp/j-east/article/200116/000020011601A0563620.php (paywalled, but the abstract says enough)
@Mike Ross: What do you think about the red (very low) frequencies in the White Island Drum plot http://www.geonet.org.nz/p/volcano/drums/latest/wiz-seismic-combined.png ? And: has it been downscaled?
It’s possible the gain/sensitivity has been reduced, or the instrument messed with, around the 9th – but the low frequency stuff is interesting. There were signs of that earlier; I would take that signal to indicate fluid movement. Whether it’s hydrothermal or magmatic, I’m not sure at this stage. In recent weeks I’ve also seen periods where there were a lot of red lines on the tremor plot. Those indicate discrete local seismic events; quakes, or possibly stronger hydrothermal events.
It certainly bears watching. If GNS suspected something was up, they would raise the alert level or post a report. Nothing yet…
I will have my own Wellington area geophone online soon. Same setup as Jon Frimann 🙂
that’s cool, don’t forget to stick a link to results here somewhere when it’s up and running 🙂
And in another part of the world some degassing is ongoing at a lava dome of Mt. Redoubt, Alaska: http://www.avo.alaska.edu/webcam/Redoubt_-_Hut.php
Check out Stromboli: http://www.ct.ingv.it/en/webcam-aeolian-islands.html
& there is quite a glow on Etna: http://www.lave-volcans.eu/webcams_etna.php?numero=2
HT showed a small rise.
Oh wow Karen! That really is quite a glow. Look at this cam now.
http://www.radiostudio7.it/webcam.asp?web=2&id=2
Wondering if it will start to dribble lava? It is certainly cooking well up there.
How odd, someone just moved the cam so it is showing nothing!
Yay!!! She is chucking out her rattles again! Some nice sparks showing up. Thanks for giving me the warning Karen as i wouldn’t have thought to check so soon.
Stromboli joining in the fun too. Thermal cam showing up well.
http://www.malinpebbles.com/Images/FOTOS/Meine-Webcam-Seiten/pubweb/Etna.htm
I can’t get any of the Etna web cams or tremor thingies to work. 😦 I bookmarked a load of them last year, but the results are as reliable as the electrics on my old Lancia Thema. Even Newby’s reference seems stuck on 0:11am never to change. Am I doing something wrong?
Certainly Clive the Radio Seven link I gave is stuck on 0:11am for me too. 😦
This one was showing a lot of activity earlier but not looking so good now.’ See if you can get it now.
http://www.lave-volcans.eu/webcams_etna.php?numero=2
If not Stromboli is having a bit of activity, maybe you can get this link?
http://www.ct.ingv.it//sezioniesterne/webcam/Webcam.php?Vulcano=Sqv
or else the thermal cam?
http://www.ct.ingv.it//sezioniesterne/webcam/Webcam.php?Vulcano=Sqt
If you can’t get any of these then I think you do have a problem.
Tremor does seem to be very slowly rising on Etna so if it continues to go up it may be worth checking for ones who are up while I am getting some sleep.
http://www.ct.ingv.it/en/tremore-vulcanico.html
Thanks Newby! Yes, these other links are good, so it’s not really me after all! The sad thing is I need to turn in now for work tomorrow. So I won’t get the chance to monitor them. Anyway – thank you for your help! I’ll catch up with these tomorrow.
Yep, same here. retired so don’t need to get up for work but must get some beauty sleep now. 😉
Badly needed as I get older! 😀
At least you didn’t have corrections officers gathering around you asking what your business was when you pulled into the parking lot. I did. They left me alone after I told them. In fact, one was quite happy to see me. I was there to repair some of his stuff.
Given their work environment, I can understand them being edgy.
Popocatepetl is emitting ash at the moment: http://www.cenapred.unam.mx/images/popoTlamacas2.jpg
OT: Again. More Smellivision™
Today… freshly plowed dirt. Hundreds upon hundreds of acres of it. And what memory did it evoke? Dirt clods. Specifically, playing with the cousins in the field in what was an impromptu softball game using “Horse Apples” for the ball. (Osage Orange). Rather than having to retrieve a pop fly when the batter connects, there is a spray of juice and bits of horse apple flying about. Eventually is just devolves into a dirt clod war. Mostly dry, these clods easily shatter on impact, so even if you hit someone square with one, it turns into a lump of sandy soil when it hits.
“devolves” is an improper usage. “disintegrates” might be a better word, though it just becomes a wad of sand when it does.
Yay! I get to write On Topic! (of sorts).
Right now, there is a small going on near the North Coast of Taiwan. (24.716390°N 122.788404°E)
This is in the back arc basin stretching from Taiwan up through Japan. The nearest volcanoes are about 90 km away. This is a spreading center, which tend to form in back arc basins.
This FYI is brought to you by the the letter seven.
Don’t understand this last sentence. ❓
Some quakes over magn. 4 these last days in Taiwan: http://www.cwb.gov.tw/V7e/earthquake/quake_index.htm (national meorological institute, report til 16 april) and http://geofon.gfz-potsdam.de/eqinfo/list.php .

Letter 7=G 😀
It’s a play on sesame street and an old Cheech and Chong comedy bit. “seven” not being an actual letter is completely incorrect, and illustrates just how blitzed out of their skull the two muppets in the comedy bit were.
I had a less than optimal day yesterday and felt just as non-functional. Anytime you have to break out a drill to remove the rivets holding the frame of a UPS together, just to get the @#$@#$ batteries out, it’s not a good day. Flakes and dust from dried electrolyte that gets on your skin turns back into acid when it mixes with sweat… and that gives you a burning sensation until you get it off. I think I may add a small container of water and baking soda to my collection of tools and stuff that I carry around. A small rag moistened with it would neutralize the acid and stop any further burning.
thanks for that, might add baking soda to my first aid kit in the car
“Early to bed early to rise, makes a man healthy, wealthy and wise” Yeah Right! it don’t work for Husband….you ever met a wealthy Postman? As for women all I get is to miss Etna’s shows!
Now have a look at this GPS plot. Look at the dark brown one .It’s labelled Hau ( Haukadalur) am I right in this presumption? Now East trend is up a little, North trend is definitely very down and Up is….well very upward. Am I right I thinking this is GPS for Lady Hekla? if so…. Don’t go for a hike up Hekla Irpsit…. 😀 taken along with Isak readings it seems ominous.

Hi Diana, Islander mentioned this in the last post – and also told us not to go hiking there!
M2.1 in West, Texas 😦
http://earthquake.usgs.gov/earthquakes/recenteqsus/Quakes/usb000g9yl.php
That’s from the explosion.
That was my point…
Equiv to about 1.2 kilotons TNT in energy release.
The fertilizer plant blast in Texas was measured as a 2.1 magnitude EQ. I hope not to many people got hurt although the current reports are not good. http://edition.cnn.com/2013/04/18/us/texas-explosion/?on.cnn=1
What a dreadful accident. I am just hearing reports on the morning news. My thoughts with all caught up in this.What Brave fire fighters and rescuers. Deepest sympathy to the families who have lost loved ones.
Oh Dear!!! USA having a very bad week indeed!!
The Daily Mail is always a bit of a sensationalist newspaper but the pictures on here speak for themselves. They don’t need to sensationalise this one, it is a disaster in it’s own right, oh if only it had just been a true earthquake!
http://www.dailymail.co.uk/news/article-2310825/West-Texas-fertilizer-plant-explosion-leaves-dead-100-injured.html
“Oh Dear!!! USA having a very bad week indeed!!”
It’s what we do.
Here is a vid from years ago where a rocket fuel plant goes up. It’s a much more distant view than the Waco plant explosion. You can make out the shockwave quite easily as it crosses the desert floor.
And, here is a picture of the USS Solar. I had long wondered why the pier at Leonardo was so flipping long. At three miles in length, you are not allowed to drive walk or bicycle to the ships berthed at the end. You have to take a bus. On one return from deployment, we arrived just in time to have blizzard conditions greet us. When we got to the base of the pier, it was actually quite pleasant.
Here is one reason why it is so long.
There is a monument next to the admin building there. Allegedly, it’s a piece of twisted debris from this ship, put up as a monument where it landed.
I’d noticed! ;(
😦
How awful. Thoughts with the victims, their families and friends.
We had an explosion like that in France in 2001 in Toulouse (South west). made huge damages and killed quite a few unfortunate people. My sympathy to the people over there.
They happen occasionally and often claim many lives 😦 looking at the footage here, the fact that the plant was close to a residential area and also that the USGS measured it at M2.1 makes me afraid that many people may have lost their lives there.
The fireworks warehouse that blew up in Enschede, NL in 2000 comes to mind, leaving 23 dead, 1000 injured and flattening a whole neighbourhood. The Waco blast seems even larger….. so my sympathy is with all involved.
(first explosion at 0:54 was the smaller one)
Sadly so true El Nathan. I really fear that many fire-fighters may have lost their lives in this one as they were so close fighting the original fire.
I have a nephew working on an oil refinery, he always speaks of the bravery of the company fire-fighters. As he says, “If we hear an explosion we have to stop all vehicles and run in the opposite direction as fast as we can. I can only admire the bravery of the fire-fighters who must run or drive as fast as they can TOWARDS the explosion. ”
My thanks and admiration to all fire-fighters everywhere in the world!!
And all my sympathy to anyone caught up in this dreadful incident.
And as a side not, why oh why do they build such places close to residential properties, or vice-versa?
I was just wondering about that Newby – whether any thought was given by the planning authorities to the danger. I don’t know whether the factory or the houses, nursing home, etc came first but they shouldn’t have been that close to each other. The problem at Bhopal was that a shanty town had grown up round the plant after it was built. No new building is allowed near to where I work – or the nearby “fireworks” factory.
The radio news has said this explosion was heard 45 miles away and there are fears that “scores” of people are dead. A terrible accident and my sympathy to anyone affected.
We had one 20+ miles to the north of us in 2005. Recall being woken up by the explosions. I think we were lucky and not many were hurt as it was around 06:00 am on a Sunday.
http://en.wikipedia.org/wiki/Buncefield_fire
I remember that Buncefield explosion and fire Karen.
I was on spring break working for a Farmer here in the Grande Ronde Valley of NE
Oregon when our local fertilizer plant caught fire. (1971)-It had an old (wood) grain elevator full of fresh Ammonium nitrate. Fortunately the fire was caught by the local FD
The chief knew his stuff-he was an ex-USN (Lurk will appreciate this.) had experience
with fighting hot nasty fire before-Shipboard at Okinawa in 1945.No one hurt,but they evacuated the area around the town of Alicel for 5 miles…I was glad to see the way they store that stuff changed after that-plant’s gone now…
Ammonium Nitrate is virtually the same as Dynamite under certain conditions..
Thoughts and prayers to all who are dealing with this..
In my firefighting days i never had to deal with that sort of fire…wildland has its own
cachet of nasty surprises …
He probably was a student of history.

Now something on topic. Worth keeping an eye on the ETNA cams today (The few that are working!) as the tremor is still slowly rising. Etna definitely seems to me to have entered a different type of activity lately.
http://www.ct.ingv.it/en/tremore-vulcanico.html
More background tremor showing on the Real-time seismic signal too.
http://www.ct.ingv.it/en/real-time-seismic-signal.html
Activity increasing on Etna, now is the time to start watching the cams if you can.
http://www.ct.ingv.it/en/webcam-etna-en.html
Hi Folks, I have been very busy at work for a few weeks and have ot had any time to “webcapture” any volcanoes…Based on recent posts i have restarted a web capture of Etna, however many of the webcams are down, and i only have 3 min updates on the one am i watching
Popo looks quite clear and update frequently, so i have set that on 60 sec updates.
I was thinking of an idea of a simple web page that allows folks to enter a link to a webcam and the web-page then goes an runs a service (ie the perl script that i posted a few weeks back) and after some time (specified by the user) a second service converts the jpegs into video and emails it to the user, via something like mutt (which is a linux command line email tool). That way people who come to this website, and see some activity and capture it for all to see.
Off course there are some security issue that can be resolved: ie handling of peoples email addresses and possible denial of service because the system would be allowing people from the internet to start storing lots of data on the server in the form of jpegs and mp4 files.
Do you think there’d be much interest here for something like this?
/Greg
Hi Greg, not sure it is something I could or would use personally but it sounds a good idea for more computer literate people than me.
Hi Greg
This is definitely interesting, but I think this should be discussed in terms of resource
Update on Etna, tremor still continuing to rise. A lot of smoke and ash on visual can and the thermal cam is showing white hot to quite a height and it appears lava is starting to creep down in places.
http://www.ct.ingv.it//sezioniesterne/webcam/Webcam.php?Vulcano=Emot
Habemus paroxismus! Popcorn?
But the smoke is still black! 😆
BTW the often mentioned INGV volcanologist Dr. Boris Behncke is also talking about a runup for the 11th paroxism happening right now http://www.flickr.com/photos/etnaboris/8660147486/in/photostream
And INGV homepage update is also talking about Stromboli heating up with “spattering and low lava fountaining”.
Both volcanoes are monitored by staff from INGV in the field.
There she blows!
Yes, a lot of ash, black and some white smoke too, but we won’t get to use the white smoke till the lava fountains appear – so this is a small paradox …. hm … but funny one …
http://en.wikipedia.org/wiki/Papal_conclave#Fumata_nera_and_fumata_bianca
hmm.. http://www.guide-etna.com/webcam/
not so small me thinks.
Certainly not so small looking at cam 5 on that site!.
So much smoke now even the thermal cams can’t pick up the heat signatures!
sorry, that was meant to cam no. 5, the big picture.
She does indeed Bruce!
Showing the White and Black smoke on this cam now.
http://www.etnaweb.net/nunziata/webcam.php.
Tremor looks to be peaking now.
http://www.ct.ingv.it/en/tremore-vulcanico.html
Rats, was hoping Etna would wait until I got home. Oh well.
it’s not today’s but it’s a pretty good one from 3 April so I guess you can just pretend. 😉
Thanks for that Bruce, it was better than what I saw today anyway. Today was far too obscured by smoke and ash for me to see much. Hopefully someone will post a good one of today on You Tube later.
Great video. And would it be wrong to admit that I’m somewhat consoled by the fact that the main paroxysm today was mostly obsucured by clouds so I wouldn’t have seen much of it anyway?
😀 Not wrong at all! Frustrating for the rest of us watchers though.
The MONTAGNOLA VISIBILE MAP was not too doog to view it from, the main event was obscured by cloud…ash or normal clouds i cant tell.
Thermal cam now showing that the eruptions covered a large area in hot ash and other ejected material.
Unusual I think, Etna’s tremor appears to be reluctant to fall right back this time and in fact seems to be trying to rise again. Perhaps she wants to get back up there before she loses her nerve. 😀
Well there are either elks running around EBCN (very unlikely), or the signal is picking up a bit:
http://www.ct.ingv.it/en/real-time-seismic-signal.htm,
Or not. INGV have updated the plot.
Yes, acc. to this article http://www.meteoweb.eu/2013/04/eruzione-etna-spettacolo-furioso-per-due-ore-adesso-la-quiete-nube-di-cenere-su-malta-le-foto/198391/ (in Italian), the ash cloud went south til Malta.
Acc. to the a.m. text, he paroxysm was a typical one with lava fountains up to 600 m, but not well to be seen because of (eruption) clouds, the paraxysmal phase from around 13.00 to 15:00 Sicily time. Esp. remarkable was the noise, which had people on the western side of the volcano leave their homes in panic (if I understand that right). This noise was even heard in Syracuse (distance about 80 km from Etna summit).
Earlier VAAC report:
People in Sicilia (FB) are hearing rumblings from Etna getting louder and since the tremor is rising again they suspect another paroxysm could be underway…
http://www.ct.ingv.it/en/tremore-vulcanico.html
And this has been posted by Gigs at FB Tuff Team:
http://www.livescience.com/28821-yellowstone-supervolcano-bigger-plume.html
The EMOT thermo cam shows red (heat) colour again within the NSEC.
Meanwhile Stromboli is also doing something strange: http://www.ct.ingv.it/it/webcam-eolie.html (Vulkanian explosions?).
& on the saddle between the NE and NSE craters (Etna).
Stromboli appeared to have a lava flow last night as well.
There is also one to be seen at the thermo cam I think.
And in case, you have been wondering if there is rockfall or so down Valle del Bove (Schiena del Asino cam), it seems to be a big lava flow, acc. to this: http://www.meteoweb.eu/2013/04/eruzione-etna-il-punto-della-situazione-avviso-di-criticita-elevata-dalla-protezione-civile-altre-foto/198422/
This looks even like a small pyroclastic flow down Sciara del fuoco at Stromboli: http://www.meteoweb.eu/2013/04/etna-e-stromboli-danno-spettacolo-in-contemporanea-doppia-eruzione-in-atto-le-immagini-in-diretta/198317/ (no expert)
Fotos from today’s Etna eruption, NSEC and lava flow into Valle del Bove: http://hraun.vedur.is/ja/englishweb/gps/cts/siszall.html
I am not really an Etna fan. I don’t know why maybe because I have been spoiled with Iceland’s and El Hierro’s brilliant streaming live cams.
However Etna has put on a very ashy show today and is ,according to the thermal imaging at ING, very hot! http://www.ct.ingv.it/it/webcam-etna.html
Stromboli still appears to have a lava flow and Vulcano is degassing. All in all Italy is being lively.
I hear an excellent radio interview with a geologist from BGS (British geological Society) Dr Roger Musson about the Iranian Earthquake This week.
You can also listen to it again here. It was a good interview and described the area brilliantly…..
http://www.bbc.co.uk/programmes/b01rw3yh
And apropos Iceland and the Iranian earthquake: The Eyja tremor plot at Smörgil looks a bit like the quake failed just so to initiate some activity at Eyjafjallajökull again: http://hraun.vedur.is/ja/oroi/smj.gif
Station Midmörk (between Eyjafjallajökull and Hvolsvöllur, i.e. to the west of the volcano) also shows interesting activity: http://hraun.vedur.is/ja/oroi/mid.gif
Second Hekla “Volcanic Field” quake today.
*true!*
This be Anno 1970, 1981, 1990/1, 2000 the plume should already be 50,000 feet visble?
Whats wrong, is the magma not hot enough?
*stirs* 😉
Perhaps too many seismographs now? Registering every little burpburp? 🙂
I think you are reading them not for what they are. 🙂
The SIL graphs have/show graph (formulas) that “stores” unrest data, “unrest” now is compared to “calmer” before, never knowing what comes afterwards, but I really do not know the formulas used. 🙂
(Every time you hear horses runnning, do not think they are Zebras.)
The only thing (I think) Eyjafjallajökull is doing on inside is getting cooler. 😉
I know, can’t be such a lot left over inside Eyjafjallajökull:)
Arternoon all, been a very busy week at work, so no time to comment much… Two days off now 😀
I may be shooting myself in the foot here, but is anyone watching Colima at the moment? I keep getting a 503 error (server maxed out…) Which makes me wonder…
I didn’t get the image neither.
I’m on now, the volcano is almost completely obscured by clouds of something…
So still wondering…. 🙂
Just had a nose around the rest of the ucol site, won’t let me see the seismos etc… 😦
There are some seismos on here. Are they any use schteve?

Thanks Newby,
EZV4 looks interesting, but I’ve never looked at it before… So it’s hard to say what it means. The webcam server is maxed out again… 😦
Another webcam link for Colima: http://www.baysider.com/Webcams/Mexico/Manzanillo/Manzanillo_Colima/ (connection comes and goes).
From this, could well be that something is going on at this volcano.
More information on Colima: http://www.geociencias.unam.mx/mexican_volcanoes/volcanoes/colima/index.php and http://volcanofiles.com/colima/
There is something unusual ongoing at the island of Vulcano, I think (no expert). There seems to be some degassing on the older cone, to the right and behind Fossa: http://www.ct.ingv.it/it/webcam-eolie.html
Most of the clouds would probably be from Stromboli (southerly winds), but I am not sure, if there is not some activity on a new place on the island also.
0.5 mag hekla the depth 4.8km
smallish, but very convincing, two quakes today, they are inside Hekla Volcanic Field (Active Volcanic Area) so anything can happen.. given it happens, if, when.
I think certainly put her back on Yellow *my opinion*
Just looking at the info on the chats, apart from the EQ’s and the raise in the grounding around Hekla, Islander did you read anything about Gas or snow-less area’s?
Maybe you should edit your tag before something happens. 🙂
For mountain having very deep magma “system/plumbing”, snow-less areas on it are “worthless” (its always hot from previous eruptions), Gas I know nothing about, and using this for prediction, one must get (I presume) minimium one “complete cycle” for comparision first, to evaluate. But I only put one tag on Hekla – “caution” today!
The first was 8km deep and the second 4km deep – does this mean anything do you think?
no *probably not*
but its getting more and more surprising nothing comes of them micro quakes happening week after week, and then the “Seven Deep Quakes of Hekla”
in last month and …. nothing!
Does not make sense. There is uplift, and its ready. Why does it not blow?
Almost beats me, save having fool of all of us. 😉
The horsefeet we hear running is defenately a Zebra running.
Thanks, Islander, I’ll keep on watching the meters. It seems to be ready to go ‘bang!’ but then it’s taking more and more strain. I’ll be looking out for horses, zebras and GeoLurking’s Black Swan! 🙂
yah
absalut 🙂
Quality is at high 60%, to low to tell to much, nothing to big was picked up on the strain,
For British readers: wonderful bit of disaster mongering on BBC2 at the moment – Could We Survive a Mega-Tsunami? To quote Private Frazer “We’re aaallll dooooomed!” 😀 😉
Ah I loved him on Dad’s Army. A true Scot! Just loved the accent and the “We’re aaallll dooooomed!” 😀 😉 Takes me back to my teenage days in Scotland. 😀
Very surprised that the documentary did not carry the usual caveats and was amazingly dogmatic. There were some big assumptions made.
& the conclusion that the UK could not plan for a tsunami event seemed to be wrong.
It was based on the fact that Japan had planning and measures in place but the 2011 tsunami was still devastating, totally ignoring the fact that the measures would have been effective for smaller events. A 9.03 Mw undersea megathrust earthquake may well be bigger than a landslip from La Palma – I need GeoLurking to advise :smiles hopefully:
better have some floaty’s handy and put some petrol in the boat
We have a plan to hike Hekla this Sunday.
I am part of a winter hiking group, and we have that plan, apparently our organizer is in close contact with the Civil protection and they said that nothing unusual is happening at Hekla.
I am still undecided to go, because of being Hekla itself. If I go it will be the second time I hike the mountain after a period of marker unrest (the first was in August 2011). My colleagues are all excited to hike Hekla, but I think knowing too much on Hekla makes me think twice.
Hekla-wise: I think tension is on the rise again. These small quakes near the top of the chamber of Hekla (around 9-12km deep). Also strain is on the rise. But nothing else. Does anyone knows the data on the GPS last few days?
Thanks to Islander on t he last post.
Diana posted another great link in the last few days, I could not find it so far. will check.
Hope this helps, I would check in the morning before going, This is a me thing.
Was it not this one:http://hraun.vedur.is/ja/englishweb/gps/cts/siszall.html ?
yes, I must have Bats eyes. Graize Inge B. 🙂
Also on the rise: http://strokkur.raunvis.hi.is/~sigrun/HEKLA.html
Irpsit, I for one would prefer you don’t go. If it was my son wanting to go I would tie him to his bed. I know Hekla may not erupt for months, maybe not even this year, but IF it did go this weekend I for one would really miss you!!! Plus I would feel bad I didn’t say anything.
You have been warned!!! 😉 😀 Seriously Irpsit, do consider things carefully please.
Like Newby I would advise my son against going. My son would have gone. I guess it’s the cautious mothering instinct.
listen to your gut feeling, if in doubt , don’t go
Your biggest risk is still probably that of hiking on a mountain: bad weather; accidents and / or getting lost (especially if the weather / visibility changes).
If you do go, make sure your mobile phone is fully charged and switched on. Don’t deviate from any plans agreed with the Civil Protection Unit.
Also take local advice yourself (Civil Protection people?) on the Sunday before you depart.
And re. American volcanoes, there is a continuation of Mt. St. Helen’s tale on the Rosetta Stones blog. http://blogs.scientificamerican.com/rosetta-stones/2013/04/18/the-cataclysm-all-of-the-trees-seemed-to-come-down-at-once/
Hi Inge B. here is a good site on the recovery of St. Helens by Weyerhaeuser Corp.
Not a commercial for them, entirely but a good lesson on how resilient nature is.
Sometimes with human help…
Weyerhaeuser lost millions of mature trees that were ready for the second or third cut
in that area.. http://www.weyerhaeuser.com/Sustainability/People/Communities/ForestryEducation/MountStHelens/PhotoGallery
St.Helen was part of my life for about 7 years after the blast…
I knew an old Alaska logger who had some experience with volcanic ash who was
hired to salvage log the blowdown. Oregon saw chain company made money while that
was going they’d go thought 3-4 sets of saw chain in a day. Not to mention
filters and masks for the crews…
I think Nevado Del Ruiz is gearing up for a larger eruption. In the last two years, it’s been showing intermittent activity with some small scale eruptions. For anybody who has been following it, it’s been undergoing a intense earthquake swarm in the last week and a half, including a m4.0 quake yesterday.
Add to that heightened fumarolic activity and deformation, and it’s only a matter of time til it erupts in my non-expert opinion.
I think the question with Ruiz, is whether it will form a larger eruption than the 1985 event (which was the largest volcano disaster in the last 50 years due to lahars), or if it will go “bigger”, which is most certainly has the potential to do. Hopefully people will have learned their lessons from the 85 disaster and haven’t re-built on the lahar plains.
Acc. to Wikipedia, the former town of Armero, location of the 1985 disaster, is a ghost town today. The survivors went to other municipalities. https://en.wikipedia.org/wiki/Armero
Link to the seismogram with the large quake
Can anyone explain the pattern of tremors at Smjorgil please? I would say it was some sort of traffic as it is happening morning to afternoon and decreases at night. Someone maintaining the equipment? A river freezing over every night? I don’t think so. This is on top of an Ice cap….helicopters working?
There is similar “traffic ” pattern at Haukadalur but I know there is a road near there.
Water, daylight hours, spring melt, possibly* not shure, something like that
Yes of course Islander. I forgot it’s spring. We have your winds and cold weather here . 😀
Water running below ice. I remember it before.
Smjörgil is a small ravine near Gígjökull, I’d suppose that the seimograph would be down in the valley of Thorsmörk, so running water/spring melt very probable. http://www.flickr.com/photos/rwhgould/5271445229/
Perhaps it would be interesting to make a sort of “guide” to the sismograms…..I am familiar with the ones of El Hierro, but theses ones are a different presentation.
I think a good idea 🙂
Very good idea!
But i cannot do that, i have as much troubles figuring the different versions out as many here.
Russian quake and aftershock:
5.7 266km ENE of Kuril’sk, Russia 2013-04-19 03:15:54 45.700°N 151.231°E 120.3
7.2 250km ENE of Kuril’sk, Russia 2013-04-19 03:05:53 46.182°N 150.796°E 122.3
This is the 4th big quake in the Kuril Island area since 28 februari
From USGS:
1) Magnitude 6.9
Thursday, February 28, 2013 at 14:05:51 UTC.
Location 50.934°N, 157.339°E
Depth 52.5 km (32.6 miles)
2) Magnitude 6.5
Friday, March 01, 2013 at 12:53:52 UTC
Location 50.938°N, 157.511°E
Depth 40.9 km (25.4 miles)
3) Magnitude 6.1
Sunday, March 24, 2013 at 04:18:34 UTC
Location 50.718°N, 160.155°E
Depth 9.7 km (6.0 miles)
4) Magnitude 7.2
Friday, April 19, 2013 at 03:05:53 UTC, (today)
Location: 46.182°N, 150.796°E
Depth: 122.3 km (76.0 miles)
It’s part of a subduction zone and an additionnal microplate is involved..Acc. to USGS, there were over 30 events with magn. 6,5+ over a time period of 40 years in the region.
At this depth of over 120 km, it will not be very desastrous, but be felt over great distances.

Hawaii’s Magma Chamber May Be World’s Shallowest

Good lord. Wife is wtching TV and the only thing on are Reptile Dysfunction commercials. “if it lasts longer than four hours call your doctor”….
… no, call your producer. You may have found that career change you were looking for.

Kuril’sk, Russia quake showing up on Hekla strain? There again there has been a large 7Mg Quake Northern Japan within the last 2 hours.
http://news.yahoo.com/magnitude-7-0-quake-recorded-north-japan-usgs-032640084.html
I am uncertain if this is same quakes. One mentioned in USGS log at Kuril’sk Islands off the North of Japan. Now Reuters saying a 7.0 an hour ago. USGS hasn’t updated to this one or it’s same quake.. Coffee # 1 not kicked in yet, only half way through it!
Yes Diana, same quake, checked area on Google earth which shows the quake, close enough to Japan to be mistaken for a Japanese one. So an early reporting mix-up I reckon.
Part of the island chain is Russian, part is Japanese and some islands are still subject to discussions on who owns what in the region – as far as I remember.
Actually they are all Russian, although Japan claims two of the main ones plus a couple of rocks. All will be revealed in a new post coming very shortly!
Fine, I am looking forward to yr. new post. 🙂
Hi … errrm, I’ve been working on a couple of posts relating to the cultural, political and, of course, the geological landscape of the Illeung Basin. Life and work has been more busy than expected so they’re not finished yet. Just wondering whether I should keep working on them or if they’re included in yours, should I stop?
Sorry, the Ulleung Basin, also known as the Tsushima Basin
Hi inannamoon – Please, please keep working away!
My thing is strictly Kurils – there’s a bit about the sovereignty of the islands, but Tsushima is a long way from where I’m writing about 🙂
ok cool – will do, they wont be ready for a couple of weeks though. Thanks 🙂
Hi Diana! I was also trying to work out what is showing up on the Hekla strain meters. Doesn’t seem to be anything local but the Hekla meter itself seems to go up rapidly just before the ‘blip’.
If you look at Jóns Webicorders, Somthing shook on all the metters at 0315. Same time as the “blip”. But nothing on the map.
Thats Kuril Islands quake, fairly certain of that, and possibly “local situation” (wind and wind direction) may have affected wave spectrum shifting it to (higher?) frequence as it passed Iceland, so it left visible trace on the Helicorders (usually it does not show?) Speculating here.
it is Friday night down under, so have drink and …
cheers mate 🙂
changes ones perspective on use of Mais (Corn)
Another eq south of Hekla:
19.04.2013 10:36:44 63.933-19.911 11.8 km 0.8 99.0% 13.6 km WSW of Hekla
Thank you, Chryphia, for the heads-up. 🙂
Interesting, that all of these quakes are southwest of Hekla, but on the other hand, it wouldn’t be good if an eruption would take place in this part of the system, as it is nearer to populated area.
BTW: Maybe we won’t see a lot very soon, there is another storm warning in effect.
Storm already is starting. This quake was “found”, it was not there on the IMO charts about one hours ago. My theory is that these Micro-quakes be precursior to Hekla eruption (altou they are in both SIFZ and Hekla Volcano Active Area, within the “flank crack system”), but it can be days or weeks left. Another take could be that next eruption fissure be from 12km SW of Hekla to 5 km NE of Hekla – 17 km long fissure ?
* and starting from Sunday morning … 😉 *
Very intresting Islander, my guess is still the 27th 😉
Have a nice weekend!
thanks, same to you
Meanwhile, Etna is not really resting.
Tremor has its ups and downs, more ups than downs lately. And the Italian media are asking if there is again a new paroxysm just around the corner. http://www.meteoweb.eu/2013/04/letna-non-ha-tregua-boati-e-tremore-in-aumento-un-giorno-dopo-l11-eruzione-di-ieri-pomeriggio/198655/
There is again some noise coming from the volcano too.
And Dr. Boris Behncke posted a new picture from the last paroxysm: http://www.flickr.com/photos/etnaboris/8660411625/in/photostream
Dumbass media… A more sound question for them to ask is:
‘Who is going to get sued next for even hazarding a guess about something geological?‘
or even better:
‘Who is enriching their pockets from not enforcing sound construction practices in seismologically hazardous regions?‘
You Tube video Etna 18th April.
Run-up ongoing for (probable) paroxysm no. 12: http://www.ct.ingv.it/en/webcam-etna-en.html
BTW: Nice video, thank you for the linke, Newby. 🙂
I don’t know if it was just posted, what is it?
Don’t know. But probably a broken steam line.
At a guess a hot water main. I have seen plenty of videos of cold ones blowing like that but that has to be a hot one because of the steam. Assume they use hot piped water as I have heard they do in Iceland. Hopefully Islander or Irpsit or someone can confirm that for me. It is certainly a pressured water main for sure. Great fun, unless you were the poor devil with you car close to it. LOL 🙂
Etna tremor rising faster than on the 18th. I reckon another paroxysm is definitely on the way. Hope it makes it in time for me to watch before bedtime as I have to be up early tomorrow so an early night if possible.
http://www.ct.ingv.it/en/tremore-vulcanico.html
She is still pretty smoky today and a small heat signature starting to show on the thermal cam. Could have been there ever since yesterday I suppose and obscured by smoke whenever I looked before.
