Answers to Name that Lava III and a friday riddle

As long my master did not show up the last few days, we are all hoping that he is just busy and that everything is OK but the blog urgently needs a new post and so i am taking this duty on my shoulders. Please forgive me, i do not have the same way with words as our leader Carl does.

Summary of the week.:

Erik repots that 3 volcanoes are more active than usual on Eruptions. Three Rumbling Volcanoes: Little Sitkin, Reclus and Tangkubanparahu. Little Sitkin lies in Alaska, Reclus is located in Chile and Tangkubanparahu is to be found in Indonesia.
Jan Mayen saw an earthquake 6,8 which is the largest earthquake ever reported in or Norway. Earthquake report has an article on this event.
Our Icelanders report that a glacial flood started coming out of Vatnajokull near Hamarinn.

Claude Grandpey writes that Kilauea started to deflate since the 27th of August.

And the GVP weekly Volcanic activity report can be found here.

Answers to NtL #3.

Name the volcano, and name the type of lava.

Answer: Villarica basaltic andesitic lava

Sheepy Dalek Name that lava III  Author: Carl, March 23th.

With the third edition of Name that Lava Carl underestimated the tricks many volcanophiles developed. Many here are real masters of a competition now called Google Fu and really deserve a black belt in this art. So the riddle was blown into bits after a very short time and we found out this image was even used in the Wikipedia article on Villarica.
This volcano is a quite active one and the current eruption is still ongoing since 2010. Villarica lies inside a larger caldera and it is located in the south of Chile close to a town and a lake with the same name. A lava lake has formed which left a glow on the web cameras. I am not giving the link to said cameras because they have been unreachable for some weeks.
If you enjoy hiking up an active volcano you can book tours, but then the guides drag you up the mountain in a long line with many other people. So many that this would not be my cup of tea to try. If you have a feeling your life is too boring you could even do a bungee jump from a helicopter into the active volcano. I am not providing this link either because in case you plan to do right that, i am sure, everyones Google Fu abilities are favorable to find out where you can book such a tour. I especially liked the last question…

Yes. You could. You’ll be signing a waiver, so we’re cool.”
Relief, i feel so much better dying after a signed a paper than i would without.

This week Alan sent a riddle to me which is really evil.
Quote Alan: ” There’s no answer to it so you can join in! It’s ‘reasonably’ eviil – well very evil – so perhaps you could preface it with ‘health-warning’!!
It may ‘run’ ’til Sunday for ‘hints’, so if they can be ‘warned’……..”

And for this week’s brain killer we have:

Of ancient origin and of violent birth, into this world I came; all but to end in fire!
With almost my Masters name, I am located near the home of a small dog!

What is my name?
Of what is this rarity composed?

  1. Just heard from our mighty leader.
    He is just really busy with work, so much work he can’t even sleep. He will return when he got this done. But everything is OK. So you will have to deal with me and my posts for a little longer.
    (( Be afraid, be very afraid 😉 ))
    I found TONS of images of dragon cakes. ( Check it out Google dragon cakes…. i was amazed!!!! – sheep cakes are totally in the minority )

    3 points, I think here!
    I never cease to be astonished how you gang arrive at some of the answers!
    Not evil enough me-thinks…………. mmmmmmmmmmmm

      • Ha ha! That is funny. My mother in law used to have 4 Chihuahuas, they were nice little dogs mostly, apart from one of them who would be nice and friendly until you got up to leave, then he would fly into attack mode…only about 8 inches tall but scared the pants off of me every time!

        • Reminds me of a very load barking dog once which I could not see. It was somewhere in the room and I was afraid my last hour had come. The dogs owner said: “Never mind, it is only Goliath!” Uhhhhuhuhh, “only” Goliath, what a disaster this was going to be.
          Then suddenly a tiny animal, a very old (but full of energy) Yorkshire terrier without teeth came out from his hiding place under the couch. He wagged his little tail and looked at me as if he smiled and said: I really scared you, didn’t I!

    • To explain a bit.
      Vp is the speed of the P phase wave (this is the fastest wave when there is an EQ).
      “Normal” values of Vp are more in the red color which means about 6 km/s.
      In our case we can see that the value of VP is decreasing, especially in the shallowest EQ swarm. This means the nature of the rocks has changed.

      • Just trying to understand what I see. The shallower quakes are dark blue, meaning their VP is slower than the Vp of the deeper quakes. Does this mean that the rock of the shallower area is more cracked than de deeper rock and that it is more difficult for the waves to pass through?

        • well, i’m new to this field but :

          spatially speaking you see the EQ location. the color codes shows phase P velocity.
          – the calculation was done direct, meaning there is no fiddling with the data? Only time and distance, so that can be challenged. The theory goes that with changes in speed means changes in the type of rock. slower speed would mean magma intrusion, but… there may be many errors it is a first try

          • Vp also changes with depth and rock type. Vp in the Ocean Crust should have values in the order of 6.6km/s to 8 km/s.

          • So it does not necessarly have anything to do with cracks, only with the type of rock, or could it be both? I (amateur) would expect it is more difficult (and take more time) for waves to pass through a cracked (or porous) structure than through an “uncracked” one.

          • And a heap of sand must also be more difficult to pass for the waves than a genuine piece of rock. In the sand (or other grained substance) waves will be reflected in all directions, in genuine rock they will go straight ahead. I suppose.

      • Would it be a huge amount of work to compare with the 2011 swarms? – especially to see if Pwave in first 2011 swarm and present eqs are same?

        • No I’ll do that soon. I have extracted all the values since the beginning in July 2011, that part took… 2 weeks ! but no I have a horkload of data to munch thru…

  3. Hi all, just to let you know im progressing well and getting stronger everyday, my strength is returning and im looking forward to chatting to you all more in the near future.Thanks again for the wonderful comments from you all, they really helped me, i hope you all have a great week-end.

  4. And to Spica, more belated Happy Birthday wishes!! I hope that you made (or received!) one of those dragon cakes. Maybe you should create a link for Vocanocafé recipes. 🙂

  5. Your ‘friendly’ demon here!
    Yes I am a Destroying Angel of late, so beware……..I haven’t found my victim yet 👿
    IT’S KELDA 🙂
    Allende meteorite, carbonaceous chondrite in Chihuahua province

    @ Grimmster 🙂

      • @ Talla

        Thanks! I was looking forward to those points. (Perhaps I’ll get one point for “close but yet so far”)

        @ Alan the evil one

        5,000 word essay required by noon tomorrow on why the alternative answer could not be selenite. (Just kidding!)

        @ Kelda

        Congrats. Well done!

        • Selenite=gypsum=CaSO4.2H2O, so a fiery end would give a heap of plaster! ie anhydrous gypsum 🙂
          Fun for youngsters is to heat a piece of gypsum in a flame then quench it to make plaster, but needs adult supervision ;cos it’s damn hot and can burn as it quenches!!

          • @ Evil one!!

            Ah, OK, get you but thought the “fiery end” was the moon eventually cooling down after the violent birth process. (Was first with Chihuahua, though, Meany!!)

  6. ‘Kelda the Gold’ has spoken!
    Here we go then

    To a pilot, this main part of a tree would show the communist side of a channel!
    What am I?
    How was I formed?

    Happy brain twisting!

    I’ve had a grand day, the new-built locomotive Tornado has been at the local preserved railway today (and tomorrow) and she is BEAUTIFUL!! 🙂

    Bold added by Spica to make it stick out!

    • Portland Stone? It is a limestone formed in the Tithonian stage of the Jurassic period when the south coast was a warm shallow sub-tropical sea and so subject to a build up of calcium carbonate (like inside a kettle) around the debris of shells and so on. This formed a kind of mud which then solidified. Favoured stone for building in London – the Cenotaph is made of it. (You can see I thought Port! and got no further!)

    • Hmm… A crown bouy is an anchorage marker. Communists are leftists, and the left side of the channel are green (red right returning) unless you are leaving, then the left side would be red.

      I’m flummoxed.

  7. Some fun on the way to Iceland and UK.

    Tropical storm Kirk is currently moving NE towards the UK, but it will kind of become just a normal storm during this weekend. It should arrive and pass somewhere between the UK and Iceland, around next Monday or Tuesday. Yeah, fun! Some tropical weather finally…

  8. Another brain teaser. Here goes. The part of a tree that would interest a pilot would be the top of the tree known as the CROWN. If you are in Port-au-Prince, Haiti (crown prince?) you can look across the Windward Passage and see communist Cuba. The passage was formed when a downthrow of a block between two faults caused Haiti and Cuba to separate. If there is a mineral involved in this riddle, I have no idea.

    • Hmm… the Mona Passage is between Hispaniola and Puerto Rico. In 1692 an estimated Mag 7.5 earthquake sank the entire port of Port Royal. This was due to the Gonâve Microplate being pushed along by the mid Cayman Spreading center… and it is the block between Cuba and Hispaniola.

  9. OT Alert … Non-Voclano stuff in this post.

    Some of you may not know this, but several years ago I was a volunteer Firefighter. I did it for about two and half years and throughly enjoyed it. At the time, our system was fully volunteer, even though the number of calls per year was quite high. In one year I responded to 300+ calls of the approximately 800 to 1200 calls that our particular district received in a year. A lot of training was involved in it, specifically in Fire Science, First Response and Hazardous Materials.

    One of the most dangerous calls that you can go on, involve Propane and Butane tanks. The danger arises from a phenomena known as BLEVE (Boiling Liquid Expanding Vapor Explosion). These occur when the container reaches a point of failure and all of the material is released at once. BLEVEs have been known to easily throw railway cars a kilometer or more away from the explosion.

    The high energy impulse of this particular phenomena has even been used in the design of FAE ordinance and produces yields that are on a par with small nuclear detonations. (Daisy Cutter, MOAB are a couple of examples) Essentially, the weapon discharges a gas on the final phase of it’s drop making an explosive cloud, then it is ignited.

    This is also where a lot of the scary talk comes from in regard to the Bayou Corne sinkhole.

    Nearby, in other salt caverns in the Napoleanville Salt Dome, are propane and butane storage chambers. Some writers have stated that a release would produce a blast well up into the size of a nuclear blast. From the amount of available energy, in the gas, yeah, but it all has to be released at once and ignited. (that’s how FAE works)

    One thing that the scary talk people tend to forget to note… either from not knowing or not caring, is static pressure. I knew that it would play a role but was unsure of the details. The storage caverns are at depths greater than 2000 feet. (0.6 km) This is from a Crosstex energy services letter. They ought to know, the storage caverns belong to them.

    In previous posts, I have noted that below 2.25 km or so, water can not flash to steam. That is because the hydrostatic pressure is higher than the critical point of water. No matter how much heat you apply, the pressure keeps it from happening. That is why I came up with the the idea (and still hold it) that the Tongariro eruption was due to superheated water moving above that level and flashing to steam.

    Similar dynamics are at play in Bayou Corne. From the Crosstex energy services letter (bold added):

    The analysis showed that a natural sustained liquid flow (e.g. hydrocarbons exiting the well without pumping) from the well is not possible due to the depth of the well, the weight of the liquid hydrocarbons, and the vapor pressure of the well’s contents.

    Calculations indicate that a column of normal butane in the well (i.e. 2000′) will exert a natural pressure, due to gravity, of over 520 psi. The pressure exerted by the butane stored in the well is less than 25 psi. Therefore, due to the amount of pressure pushing downward the well will not free-flow upward to the surface without a mechanical means for doing so, such as pumping.

    Click to access Crosstex_ltr.pdf

    I have mentioned previously, that the end result of how this plays out will depend on the solubility of salt. Eventually, the water in contact with the salt will achieve saturation and will be unable to dissolve any more. Unless that water is changed out with less concentrated water, the process will stop. The question is where that water can come from. Brine is denser than fresh water so it will have a tendency to sit at a lower level. It could be heated to make it percolate up, but the bottom of the Vulcan-3 chamber is only about 0.5 degree warmer than the top. (geothermal gradient of about 33°C per km in this area).

    Anyway… that’s my 2 cents on it.

    • Now this is something I am familiar with. Crescent City, Illinois was destroyed by a BLEVE event in 1970. I had several family members and friends who were volunteer firefighters from one of the mutual aid departments. Many ended up running for their lives. One of the them ended up in the hospital with burns. His fire helmet was just a melted blob. Fortunately, he recovered fully. The links below are a description of the event (train derailment) and a video. Quality is not great, but remember this was 1970.,%201970.pdf?sequence=2

    • I still have my helmet… it’s a memento hanging over the door to my “computer room” (essentially where all my crap is at). It bears scorch marks from a house fire I was in… the heat was so intense that sweat inside my bunker gear flashed to steam and burnt my shoulder.

      And I was still outside the house.

      If his helmet was melted to a blob… I can only imagine how hot that was. (that is true fear)

        • I was in fire control manning the phones/radios etc. there is nothing worse then when you can’t get he crews to respond, for whatever reason, or working in forward control center, distance/terrain in Australia, most of the guys/girls always said they are rather on the front, talk about stress and of course it is voluntary, still got my batches

          • Your comments have reminded me of the time when my neighbour had a fire in their house, I woke up at about 2am, becuase there was a noise downstairs…went down (tried waking up hubby..but no way he was getting up—I thought we had an intruder in the house..went downstairs, noone around but the noise was there…I could hear plates breaking.then thought, there must be some sort on animal in my kitchen cupboards, opened all the doors but nothing..then thought..ahh it is the neighbours they are having a row, throwing plates at each other…let them get on with it….(turned out it was the kitchen tiles breaking with the heat) ..I went back to bed, but then could smell something not nice, looked out of the window, was shocked to see my neighbour looking at me with black smoke billowing out of his window…I rushed downstairs again, on the way stabbed hubby in the ribs to wake him up….went next door…door was open….huge red glow from the kitchen, smoke everywhere made me realise big problem….was going to go upstairs to “rescue” neighbour, then thought ..OMG what about the Butane Gas Bottles that we all have in our kitchens…not just one, but in my house we had threee……what if they I backed off…went back to my house and called fire brigade…fire brigage arrived, but in the meantime, my husband had connected our water hose to the neighbours water outlet and put out the fire himself….fire brigade double checked everything but luckily all was OK…this is a true story…but makes me remember the recent fires on Tenerife, when the locals were moaning that they were not allowed the chance to even start tackling the fires on their own…they just had to sit back and wait for the Fire Services to arrive…so I think that the old saying that “sometimes a stitch in time saves nine”…could be true. Not taking anything away from the real experts in fire fighting, who I really appreciate all they do, but think that noone can disagree that if a fire is tackled early enough, it makes all the difference……

          • I have to agree with the early interdiction, but the problem is knowing when to leave.

            A group of us were after a fire on the second floor of a building and making good progress when the hot zone descended around us and the incident leader called for us to pull out. Turns out the fire had circled around us through the floor and walls and the whole structure was just before being “full on.” As we were leaving, I lost sight of the guy in front of me when we got to the stairs and didn’t catch up with him until we were outside shedding our breathing equipment. Turns out he wasn’t this “really nimble” person who had taken off and left us… he had fallen down those stairs.

            As we were sitting there, a small can of gun powder went off in a lower room. The owner did reloading as a hobby. It really would have been nice to know that before hand.

          • exactly I totally agree with you…when do you leave it to the experts..I, with my “superior” knowledge of the dangers involved (through my british education) led me to think..leave everything to the experts..don´t endanger youself as that could cause an even worse outcome… basically I think I was thinking,,,”when push came to shove” self protection is the only way to think.. I just abandoned ship and called for the fire brigade, however, my husband who is a local canarian, didn´t even think of that…he just approached the situation as a local..this was a matter that needed to be dealt with immediately by the neighbours……and he probably did save the day…..

      • Along the lines of unexpected explosions… a short tale for you.

        Before I left Naval Service, I had the experience of being stationed on an AOE. An AOE is a multipurpose stores ship that carries food, ammunition, and fuel in order to resupply ships at sea. The several million gallons of fuel in the outer tanks act as a protective buffer for the several thousand tons of ordinance in the inner storage magazines. (yeah, the same thought crossed my mind)

        Anyway, the ship was stationed at the Leonardo Piers in Earle New Jersey. While entering and leaving the waterfront complex, you pass by the administrative buildings there and if you pay attention, there is a twisted and tortured looking chunk of metal set in concrete near the sidewalk into the building. The plaque commemorates the 30 April 1946 explosion of the USS Solar, DE 221. Reportedly, the location of the monument is where that piece landed when the ship went up.

        If my recollection is correct, the monument is located here, next to the sidewalk

        40.417823° -74.071096°

        The old pier is here

        40.447256° -74.056023°

        And the distance from there to the monument is about 3.5 km

        Where on he pier it was located I don’t know. Judging by the numbering of the current piers, it would have been the Northern section.

        Now for the connection to history… The Solar was an Edsall class destroyer escort. The same class that my Uncle was stationed on (USS Strickland) and not much smaller than the Frigate that I was first stationed on. (USS Ramsey FFG-2). Though small by comparison to the BLEVE in your video, the USS Solar was one hell of an explosion.

        That last ship that I was stationed on, was one of the AOEs that were made from the canceled USS Kentucky BB. (would have been BB 66, part of the Iowa Class ships.) The Hull was completed as an AOE and only two of the engines were used in the Sacramento class AOEs. They were intended to be able to keep up with Carrier Battle groups. (which they were pretty good at doing.)

        The Sacramento class has been retired, replaced by the more automated (gas turbine) Supply class AOE (T-AOE) and taken over by the Military Sealift command. (mostly civilian staffed)

        And now for the gnarly. On that AOE, there were these large circular hatches at about 8 ft height that had no purpose other than being there. Turns out they were blow-out hatches that were intended to relieve pressure should there be an internal explosion on the upper forklift runway at the top of the handling elevators. That sort of thing gives you pause.

          • What? And tell the story of “Muffin Head?” I’d be sued into oblivion.

            Some of these people are still around and would not take kindly to being ridiculed by me. I’ve seen JOs (junior officers) nearly crap their pants when inquiring about what sort of radar I was looking at. When told that it was a fire control radar, he asked what it was doing. I told him “Looking at us.”

            I have never seen anyone turn that shade of white before.

          • But… on the subject of books. One memorable one that I read was “Some Birds Don’t Fly” by Gary Paulsen.

            It tells several stories about working at White Sands, New Mexico in the Corporal missile program from the viewpoint of a radar engineer.

            I read it as a kid, and later was able to find it again. Fascinating book.

    • Ringwoodite (Mg2SiO4 to Fe2SiO4): a high-pressure polymorph of olivine that is stable at high temperatures and pressures of the Earth’s mantle between 525 to 660 km depth or may occur in the veinlets of quenched shock-melt cutting the matrix and replacing olivine probably produced during shock metamorphism. (source Wiki).

  10. Ok – on the same thought wave (which is probably wrong) my second guess at the riddle is the Bering Strait that separates Russia and the United States – specifically Cape Prince of Wales, Alaska. Formed by glaciation and magmatism.

    • Mornin’ Georgiade and All x
      The Popocatapetlcam is a good ‘un, updating every 15 seconds, Popo looks beautiful right now with a nice little plume and the sun just coming up 🙂

  11. Fagradalsfjall? What about this location in Reykjanes Ridge?
    A little ongoing swarm…
    Saturday 01.09.2012 16:33:47 63.900 -22.246 7.4 km 3.1 99.0 1.4 km ESE of Fagradalsfjall

  12. Hmmmmmm.. this one is evil to the bone!
    To a pilot, the communist / left side of a channel is “port”. A port is a gate! Agate!
    A main part of a tree – trunk, limb or log (stripped of branches).

    I think it is… an Agatized Log, a piece of fossilized wood, also known as opalized wood, petrified wood, silicified wood or woodstone.

    This is a “material formed by the silicification of wood, generally in the form of opal or chalcedony, in such a manner as to preserve the original form and structure of the wood.”
    “It is the result of a tree or tree-like plants having completely transitioned to stone by the process of permineralization. All the organic materials have been replaced with minerals (mostly a silicate, such as quartz), while retaining the original structure of the stem tissue. Unlike other types of fossils which are typically impressions or compressions, petrified wood is a three-dimensional representation of the original organic material.”

    A picture on this page:

    Picture text: “Wood that is replaced by microcrystalline quartz—agate—makes spectacular specimens like this log of Triassic age at the Oakland Museum of California.”

  13. Have had a terrible day today, drove down to town to take son to a party, came back 20 mins later, my 83 year old father in law, had decided to have a shower while I was gone, I came back, blood all over the house, he has cracked his head open falling over when getting out of the shower… spent an hour and a half in the medical centre, twenty stitches later I hope all is going to be OK….but geez . it is so hard sometimes looking after elderly people…was just remembering Deannes comment yesterday about her mum…I know we all want to do our best for our old folk, but sometimes it can be really stressful…..emotionally and physically

      • thanks Spica and Bobbi for your kind words….I am not normally a sharer of bad news (usually keep everthing to myself) , something about this blog makes it easier to share a burden somehow…I am so glad to be a part of this!

        • Oh Debbie awful experience i hope it gives your father à sign not to go anymore alone for a shower big Hug! And put an extra shower mat on the floot outside the cabin i don’t no THE word in english you can get one in market or healtcare

    • Oh, Debbie, what an awful experience, but so glad that everything turned out OK. Thank goodness you were there for him!

    • I know it can’t really help much, but don’t be overly panicked by the amount of blood. Head wounds, by their nature, are profuse bleeders. Much more than one would expect from a wound somewhere else.

      Not that bleeding or head wounds are good, they aren’t. But they tend to appear a lot worse than they are. About the only thing that bleeds worse are arterial cuts.

    • Hope everything is ok now , I am now looking after my 83 year old Dad and totally understand how hard as you say both mentallyand physically it can be especially when my Dad is so strong willed plus he is going deaf and refuses to wear his hearing aid.
      Had to laugh to myself the other day when he said to me he hoped I would not keep him awake with my TV on late at night bearing in mind I have to be up for work early in the morning when at 23:20 the other evening I had to go ask him to turn his radio down as the whole street could hear it and I was trying to get to sleep.

  14. Our UKViggen obviously tried to write a dissertation on Shiveluch but could combine it with a thriller. Expect a brilliant post by him soon. ( Probably tomorrow). Wow i could not stop reading. Congratulations UKViggen.
    Dragons dont publish the draft, there is a problem with an image and i need to fix some layoutprobems.

  15. I mentioned the Crosstex letter that states:

    ..due to the amount of pressure pushing downward the well will not free-flow upward to the surface without a mechanical means for doing so, such as pumping.

    One thing that the letter also says is that the integrity of the formation (salt dome) is sound. There is only one scenario that I can think of that would be catastrophic.

    Failure of the dome and inundation of the butane chamber, which then pushes the gas out.

    That would be bad.

    On a plus side, one storage chamber is empty and full of brine. The other is only partially full and is being actively used to fill gas sales. The storage faculties are also under constant monitoring.

  16. Earthquake swarm at Reykjanes still ongoing, about 30-40 quakes by now:

    And the Skaftá glacier run is also still running: water height at 322 cm, water volumn: 276 m3/sec., conductivity went up to 400 in the meantime, now at around 300 and rising again, light absorption went up to 570, now bit more down, but rising.

  17. @All
    I am about to make an important change to VC and would like to ask your opinion.
    The rules and the list of dragons was added to Welcome to Volcanocafe by Carl some time ago but it is at the end of his long welcoming article and hard to find.
    Now that i know setting anchors is allowed in wordpress documents, i would like to change this page. And start it like this:
    Chapter 1 Welcome to Volcanocafe (written by Carl when he started the blog in November 2011)
    Chapter 2 Rules
    Chapter 3 List of Dragons
    Chapter 4 HELP How to find your way around, what useful things can be found where!
    Chapter 5 Explanation of the Menu

    Chapter 4 and 5 would have to be written by me first.

    Good idea? Yeah do it this helps getting started here? Or
    Bad idea… Don’t touch anything set up by Carl?

    • that would be a good idea, makes it more user friendly, I completely forgot, Happy Birthday, I am doing to may things at the same time, everybody tells me to slow down, just don’t know how

    • It is a good idea to put the rules in an easy-to-find place. I would even put them next to “Welcome to Volcanocafé” on top of the page. Because I think that every community needs some small rules to survive (happily).
      And.. take care of yourself (do not work too hard!!).

    • I think anything that helps to explain / sets out the ethos of the blog would be good for newcomers. Nothing should be set in stone as a blog evolves as it goes along. 🙂

    • My only tip is to make sure that the page does not get too long. Not everyone has speedy desk tops with large screens so some may not make it to important information.

    • I can’t detect descriptions of magnitude or depth in this, nor longitude or latitude. Just the station seems to be correct: Tenerife ❓

  18. These are descriptions of smells and feelings from the islanders who have reported these to Avcan.

    Enrique, smelled of bleach in the center of Sabinosa, on Main Street, between houses, for about 100 or 150 meters and just before reaching the ventita was there. Also the same smell in the road Well, the tips just before arriving at the cooperative (as intense but at a significantly lower elevation). ” (GAS => HCl, Cl2 and sometimes HF and HBr)

    => “When we went down the mountain we drove, logically, with the windows open and we both started the itchy eyes together, since we perceive the smell of sulfur. Emphasize that we do not stop the car at any time or we lowered, to give you an idea of ​​the intensity. The smell of sulfur, heavy (more than what I had perceived that the Llanillos) was in the section from just before the cemetery and along the whole way down the mountain. ” (GAS => SO2/SO3, H2S)

    => “On reaching the well, at sea level was the feeling of heaviness in the air, like you’re in the Teide. Identica feeling that on Wednesday next to the lighthouse building orchilla. Itchy eyes The time referred to, road we were past the Llanillos ”
    (GAS => CO2 and CO

    The truth is that talking about the issue of odors, Maria Elena Gonzalez Cardenas, sends us the following warning, I would like you all to read it, have it in mind, because the issue of volcanic gases can be dangerous:

    CGE => “Top bleach, sulfur and down amidst heavy air … Do not ever go into caves or tubes. At the slightest drowsiness or heavy head Come hell out!

    • ,,Could this be similar to the bleach smell people have commented on could it be chlorine?

      One year after the Eyjafjallajökull volcano in Iceland brought European air traffic to a standstill its ash plume revealed a surprising scientific finding: Researchers at the Max Planck Institute for Chemistry in Mainz found that the ash plume contained not only the common volcanic gas sulfur dioxide, but also free chlorine radicals. Chlorine radicals are extremely reactive and even small amounts can have a profound impact on local atmospheric chemistry. The findings, which will be published in “Geophysical Research Letters” give solid evidence of volcanic plume chlorine radical chemistry and allowed calculations of chlorine radical concentrations.,,

          • I just can repeat that people who have Facebook connection should incite the authors of this text to contact the authorities of El Hierro (PEVOLCA and whom it may concern), because these are dangerous gases!

          • Inge as far as I have read these people are reporting to IGN on the official forms what they are feeling and smelling.

        • My experiences with chlorine in my childhood:
          The swimming pool at school was disinfected with high amounts of chlorine. The smell made it very unpleasant to breathe. The eyes were burning, got red and swollen when you got water into them; of course you always did. Many children had to vomite in the vicinity of the pool. The colours of our swimming suits were bleached away.

  19. The evil riddle. A shot in the dark I think, but I do need to get stuff done today so one last attempt for now: . Aplite – from Beau (bough of a tree?) Port (left) in Jersey, the Channel Islands – The aplite minerals include tourmaline, topaz and fluorite. At St Brelade’s Bay there are two aplogranites: Beau Port Granite and La Moye Granite. This is coloured yellow brown to pink and contains fine crystals of perthite, and oligoclase and quartz, coloured by limonite. Other parts more rich in volatiles have formed pegmatites featuring milky quartz and pink orthoclase.

  20. OK Inge I try to think around the corner! What about this one (explanation as above):
    “Occasionally agate fills a void left by decomposed vegetative material such as a tree limb or root and is called limb cast agate due to its appearance.”

  21. Ok people
    You are getting a new post now, which i prepared for more than 5 hours because i needed to update the other pages first.
    Deal with me, tomorrow you ll get a brilliant post by UKViggen, but i need to prepare that too and thats why the post is going in NOW and if there are typos or other be it.
