The bar is open, not much seems to be happening, at least we dont notice too much. We are getting close to 1K comments on this post and so i am adding a new one.
So here are 2 images of one of my favorite volcanoes, simply because they are so beautiful!

Special update:
This is primarily aimed at Carl in revenge for his ‘musical scoria’ riddle
Feel free, all, to have a go!
How ‘strange’! Do you realise 7×0.111(recur) comes from Carl’s home!
What am I?
Where is my type locaity?

Yup, defo heating up a bit now, stuff on the move again
Fuertes sacudidas en Sabinosa. Sólo espero que no esté cerca.
Strong shocks in Sabinosa. I just hope that it is not close. (Translated by Bing)
Just wanted to say a quick Hi to everyone, and gosh darn. I popped on quick to catch up and found Elvis is starting to sing again. I have to run out so will be AFK. Thanks to you all for you comments, it really helps me keep up on things. Hugs, catch you later.
BBGN! Hi and goodbye, Hattie!
He’s really rocking and rolling now, GO ELVIS!!
Yep, look at the colours!

The one at around 20:33 looked very strong. over a 3 for sure I would think. Interesting to see the location. Looks like another sleepless night for the poor people.
They have also felt movements in El Pinar and Frontera.
Still deep though, very strange.

Judith, we would have been mad if CHIE was still offline! They fixed it just in time.
Yes it was good timing by them.
Could it mean something big has broken through and thats why all the earthquakes were nearly showing the same co-ordinates.
More about Hierro. This link was pointed in EMSC:
http://volcanoscience.blogspot.de/2012/07/el-hierro-reawakened.html
Not really sure what to think of the last update,
There was no new vent.
The local fisherman apparantly laughed their buttocks off at IGN, Pevolca and all others who got enthused by it.
It is a reef and some currents and have been there for the last few hundred years (minimum).
Big activity now! http://www.02.ign.es/ign/head/volcaSenalesAnterioresDia.do?nombreFichero=CHIE_2012-07-07&estacion=CHIE&Anio=2012&Mes=07&Dia=07
Getting very interesting now, something has defo given way a bit now i think, whatever was blocking stuff has now given way i think.
Drat, I should have an early night but no way until this calms down a bit.
Changed my mind about going out. This was more interesting.
I hope Hailey is soon back so I will have a bit of a life
Carl, tomorrows post is almost ready but it could be, that you better put an update on Bob in.
I will check in the morning, or afternoon and decide.
But right now it seems like this will be another of those very large intrusions and nothing more.
What? volcano beats beer?
I agree im riveted to the screen, my poor f5 button
Hiya Carl, your thoughts on what may be going on!!
Pressure has risen enough to start a new wave of magma intrusions. This time around it is slightly higher up, like the pressure is hitting the roof right south of the Lighthouse.
If I would guess I would say that Elvis will poke his head up around that spot.
Also, I think the magma is back in the direction of the lighthouse and has stoped going southwest.
But, I would still say it is a bit away before an eruption starts.
And, I wonder what that last LP was. 4.5?
LP again.

3340 for me…
Another 3.0 mag as expected. A few more to come when they ccatch up too I think.

still deep
Another 3.8, getting bigger as it goes on!

Hmm, they seem to have missed a few out there and they have updated that latest one really quickly. They must be getting a bit worried tonight.
They have put in one more now, a 3.2
18 km slightly shallower than most of the recent ones too.
Now this is more interesting. Let’s see if they now become shallower. Has it just broken further into the strata in which case they should remain deep or broken through and up ?

nice….
Right, finally calming down a little. Bed for me. Night all.
Looks like the intrusion is about to be over for this time. I guess the delamination could not continue for long before running into rocks of a type that is not prone to cracking. Like a small layer 1 to 2 km up was suffering an intrusion.
Might be the first “step up” of the magma.
We will see in the end.
And now I will go to bed, have a nice one everyone!
i ll save the post as a draft,so it would be ready.

One last word. 5 quakes over 3. mag. a bit of a rude awakening for the people of El Hierro.

And all in just over half an hour too.
Actually they just updated it. 6 quakes now between 3.0 and 3.8
WOW That has now updated to 9 quakes over 3.0 in just under an hour. That is one big lot of movement for El Hierro.
And this don’t stop!
OOPS. you are right luisport, postpone bedtime yet again. *Yawn* I will give it 1 hour more maybe. Hard to tear oneself away.
Still more incoming it seems
http://www.avcan.org/varios/sismos/AVCAN3644.jpg Seems to be moving East
I just get NOT FOUND on that link.
oops sorry, working on it
Ta!
http://www.avcan.org/varios/sismos/AVCAN3644.jpg
There ya go, sorry about that
Thanks minilurker. Seems to be moving toward Bob’s old vent doesn’t it. Wonder if the trend will continue?
The blogger on the german blog said today that he thinks it will end up in the old place
http://elhierro1.blogspot.co.at/
look at the above you tube a you tube film of 07-06-2012
Looked like that showed Bob’s old cone at just above 100 metres depth. No sign of any degassing or other activity though.
I think its heading towards Bob, or thereabouts, its just taken a different route i think.
i think it to spica when you looked at the above you tube film and you looked it again and again i think that Bob is trying to come out
One of the things that I have been curious about… is what is the ambient temperature under El Hierro.
Being along the Canarian Hotspot, it should have a higher geothermal gradient than you normally find in oceanic crust.
Finally… I found some answers. They aren’t the best answers, but they put us into the ballpark so that we can at least think clearly about what the strata is like down there… where the magma is moving around.
This also gives us a bit of insight into what some of that cracking and creaking is… strata heating up from the magma intrusion.
British Petroleum did some exploratory work off of the Moroccan coast a few years ago. Yes, that British Petroleum (BP). From some of their data, we can make a more educated guess about the geothermal gradient along the Canary Hotspot.

ERRATA, the two holes are about 400 km from Lanzarote, 800 km from El Hierro.
Corrected version
http://i49.tinypic.com/2eqb2f8.png
makes one think, Hawai comes to mind of continuous eruptions, it is going on under El Hierro, (he Canaries) for a number of years now, with a Northerly trend as the hot spot moves or should I say the plate, it has to come up at some time and fill the gaps
http://live.mila.is/jokulsarlon/ A nice picture im going to sleep a very good night everyone!
Oh!! They added a badge for winning an earthcam award .lol. Did they ever check the text that used to be attached.
Goodnight Dean and goodnight to all from me too. I have the sound of the heavy rain as a lullaby.
BBGN all
BBGN to all what are going to sleep.
love the sound of rain on the roof, especially after a dry spell, makes for a night of ….
Arg! Cat on key board, he deleted my post and is now trying to hairball. Anyways, was that a hard thing to do, to have to run out right when Elvis was performing. I had a quick scan through the comments and there are way to many to comment on, so I figure I would just put a general one in here. Carl wow it’s hard to believe that we are so popular, congratulations to you and everyone who contributes. I was clueless on the riddle. Am going back now to have a better look at all the posts.
Just hoping it will be able to vent safely. There must be so much gas and magma bumping about, 20 kilometres below – a long was down, but a lot of expansion going on. Bob was much smaller and was venting steadily when the quakes reached 10km. Elvis is a much bigger star attraction in the making… And always remembering – El Hierro is like a steeple and the land above sea level, is a small iron cap on its top.
The magnetic measurements are fascinating. It must be riddled with and threaded with lava tubes to give it a sinuous framework of mostly congealed crystallisation. How might the heat rising change this composition?
I guess that’s just one of the many questions we don’t yet grasp the possibilities for.
Best wishes all – and goodnight
And now one for the hard core Geo people.
http://i47.tinypic.com/2m6l7ns.png
This is the likely environment where the quakes are occurring *between the green lines).
The thermal gradient may be a little low, but it’s a best guess based on those two boreholes along the Hotspot track North East of here.
For pressure, the general trend is based on the mass of granite, but I have seen texts that use basalt for oceanic crust. What sort of material is down there reacting to the magma is probably low to mid-grade metamorphic rock (that phyllite slate and shale) and in regions where magma has previously been intruded… probably as high as schist. And of course, whatever sills and dikes have been put there in the past.
Thats my guess.
I am learning heaps from those charts, I will look at them again and again, with time we will learn what is going on down there, puts a ..to solid ground under our feet no matter where one is on our blue marbel
Thank you Lurking, how on earth you knew that I wanted these two plots I will never know. But they are perfect for a post on balloons that I have been thinkering with in my head.

CHIE vs CTAB ….
seems that Ctab is closer to the show???
The seismograph CTAB is not on this IGN list: http://www.ign.es/ign/layoutIn/volcaListadoEstaciones.do?codT=GPRS&desT=Estaciones%20s%EDsmicas%20de%20transmisi%F3n%20digital%20GPRS/UMTS
Could it be a transferable station?
