Sheepy Dalek – Beach Edition

One happy dog, one second before…

A wise man once said; ”Life is like a beach, then you die”. After that he made surfing popular and inspired almost all surf-music.

This is the time of year when every sensible person in the far north dream about going to a warm beach, drink nice drinks, and fall asleep with a book over his or her nose, slowly broiling to the famous Tizian lobster-red.

I am a bit suspicious about the whole thing. If life really was that good something would be bound to happen to you that you would not like. On the other hand, you could bet someone else would be getting really happy when you get hit with…  And by the way, doesn’t the dog look terribly happy?

Regarding the wise man, I am of course talking about the original surfer dude, Duke Kahanamoku. It is said that when you are drowning in a wave you will see him. I wonder if the woman saw him when she had her close to death experience.

Who shrank the board? From this sensible size of board to todays plastic minis…

    • Interesting video, Tyler, thanks for posting! It says on YouTube that the graduate student who put this together had to speed it up 100x to make the seismicity audible. I wonder what it really sounded like up close.

      I had to look up Okmok to figure out where it was. Turns out it’s close to Cleveland Volcano in Alaska, which had a bit of activity in December. I think that Cleveland has been discussed recently over on Eruptions.

  1. Arrgghh! (clutches chest) My team was crushed in the second round! (sobs into pillow) Oh the humanity!! (sob-sob-sob) (lays head on bar) Barkeep! I need a Bloody Magma drink!! Make it strong!

    Just you wait! (grits teeth). They’ll be back! They’ll get strong over the off-season. They’ll come back and make Brady pay! Lookout!!

    • Oh dear! This is what comes of following sports teams. Never mind, they will soon be back to winning ways! Commisserations!

    • It’s almost like Bob has a chamber that empties out, then refills itself. Bob runs low, then pumps magma from another spot, causing EQs, then when he’s filled again, more activity. Where’s all this magma coming from, and going to?

      I wish the person who has the ringing in his ears from activity would take a trip around the island and use his ears to pinpoint possible spots! That would be interesting.

  2. Actually all stations are showing significant inflation but in last couple of days there was sudden deflation. This is something that can happen before eruptions when magma degases itself, and releases some space. What I would like to install in Hekla would be to monitor CO2 and Sulphur emissions near the summit.

    • Good thinking Irpsit. This may give a day or two warning rather than less than an hour.!
      How is the weather up there in iceland? I think we have some of your Ice. it was -6 C in my car yesterday morning.
      Do you want your Ice back? 😀

      • I am sure that IMO or the Institute of Earth Sciences (Univ. of Iceland) do have gas monitoring stations installed near all the important volcanoes. Would anybody perhaps have a link to them?

    • There are gas-monitors there.
      I do not know of any link to them. Perhaps Wagabond knows if IMO is having them online.

  3. Betty
    I agree and wish we could find out where this person lives on the island.
    I also wish we knew hwere all this magma is going to.

    Irpsit
    Are you taslking about inflation and deflation on the stations on El Hierro?

    • Well, we do know where it is going, towards Bob, and being erupted there. Very unlikely that there is much else going on. It is actually very hard for magma to move much in the first case (the largest majority of it getting stuck), and when it actually does, it will take the path of least resistance, so here the easy path out already opened by the existing vents. Nothing much will change unless these become permanently blocked.

      • I disagree. We really do not know the structure of the plumbing system under Bob, except that Lurking and Karen have done some outstanding work attempting to unravel the mystery. The experts themselves do not know for sure, there being discussion between a single magma chamber, two magma chambers, or a series of many pockets. Yes, Bob is erupting. Yes, the path of least resistance will be taken. Not sure what you mean by “it being very hard for magma to move much in the first case (the largest majority of it getting stuck).” Do you mean, that once it has erupted, it cannot move much? In that case, I’ll agree, because Bob is working hard at building a wider base and reaching the surface. The danger will be what Bob does when he finally comes up. I am not sure how many vents the top of Bob has, because those that know are not sharing their data. We have EQs in areas away from Bob, possible fumes away from Bob, and continuing harmonic tremor which has not stopped ever and now increases. Although everyone hopes for the best, to say that we know that nothing else is going on is just not possible at this point.

        I am not an alarmist by nature, but I am vigilant when I need to be. I am extremely curious to know why bathymetry charting is not being shown. This volcano is 1.8km to 2.0km offshore, depending on where you are standing. That is very close. This thing is dangerous. How close is it to the surface? The entire island wants to know. You say the lava is not traveling very far? Then it’s building up a cone. HOW CLOSE IS IT TO THE SURFACE? Or, is there a second vent in El Golfo? Or off Roque Salmor?

        This is a complex eruption for the following reasons: EQs started on one side of the island root, then moved to the other side; it started with shallower quakes, then moved down, then moved up; whenever Bob slows down, EQs start up again, with or without chugging, which is probably not related to this peculiarity at all, anyway; the probability of ring fractures exists; the composition of the magma is disputed; there is the history of two, possibly three, other much, much larger volcanoes in the vicinity; and there is a huge fault, although dead, which is long enough to be a factor in analysis.

        This volcano was most likely going to have a limited supply of magma. But, it has already gone on for a long time. Where is the magma storage occuring? This Bob is turning out to be a very large fellow. He could quit in a heartbeat, but he’s just not. And if we start having really deep quakes again, it could be a second cycle of magma mixing and rising.

        How tall is Bob? This would be helpful to know. I might bite if I were shown the progress Bob has made. But, I am starting to suspect a humongous volcano is coming up. (Blog standing caveat: I am not an expert.)

        • About most of the magma getting stuck.
          Your average volcano will only erupt 5 to 10 percent of the inflating magma. Grimsvötn seems to pump out between 25 and 50 percent. Same goes for Hekla. But they are the odd ones out, probably due to them erupting so often that they are kind of being a bit worn out down there.

        • As Carl stated most of the magma coming up from the mantle just gets stuck in intrusions (like one-way-pockets for magma).

          What did you mean by the two or three bigger volcanoes in the vicinity? Tenerife? La Palma?

          Bob is just a vent of a large volcano, it’s in a way the whole island, a composite volcano built up in at least 3 different long eruption phases, so it does not have to “come up”. It is just not excluded that it will open further vents, and possibly also on land. It is also very probable that Bob has submarine brothers and sisters, very deep down in the sea, so that we can’t see them without bathymetry and even that – I don’t know the depths they can reach with their apparatus. Active submarine vents could also be in the El Golfo area of course.
          But then – my caveat – I am no geologist neither.

        • “…it’s in a way the whole island, a composite volcano built up in at least 3 different long eruption phases…”

          Not “in a way” it is the whole island… and Bob is just a flank vent.

  4. Good Morning Judith. Dawn is just breaking over Bob and my Icy Garden. I have blackbirds and a robin queueing up for food and water, poor things.
    It looks much warmer on El Hierro. Well below OC here

        • on a GB keyboard

          hold down ALT
          then on the numberpad (not the numbers at the top of the keyboard) type 0176 then let go of ALT and you should get °

          if you ever want other funky characters
          go to Start , select Run, then type charmap
          and hit OK
          it should bring up a program called character map showing a big list of characters
          click on the one you want, click select, copy and then go to the place you want it and paste it in.
          Also worth checking in the bottom right hand corner – where you should see something that says Keystroke:Alt+0176 (or something similar) and that tells you how to get that character without opening the character map.

  5. Good morning, Diana!
    Since you are the sheep and plant expert, and since we are still in the bar, I have to ask if you saw the fact sheet that KarenZ posted back at January 15, 2012 at 00:34, and my reply. I was fascinated to read that young sheep eat “swedes”, hopefully you will reassure me that it is some sort of plant or a typo, and that Carl is not in danger….
    Now I must go to bed, 2 am here and fading.

    • OMG! I think it’s time to exit the bar, I nearly choked on my orange juice to think that Carl might be devoured by his sheep! Although from my experience, sheep will eat almost anything.
      A swede in this case is a yellow turnip or Swedish turnip. During my childhood in Wales, swedes were used fairly extensively as a root vegetable – mashed (alone or added to mashed potato), in stews & casseroles and in soups. Can’t say I’ve used one since coming to Australia……. and haven’t missed the experience.
      Now I have to get rid of the bizarre image of Carl’s rear end being nibbled by a sheepy thing!

  6. Good Morning Diana
    I am just watching the sunrise over the Atlantic Ocean (we live on a hill overlooking the sea) it was 25 degrees here yesterday afternoon.

    I am freezing here when it drops to 16 degrees on a night the tiles are freezing to walk on !!!

  7. Ciber-Mul

    Are these blasts of explosions as shown on the graph for this morning showing though that the magma is getting blocked somewhere and is this not something to keep a close eye on.

    • Certainly different. And (difficult to really assess due to the angle) but the eruption site looks more turbulent. Or am I seeing things?

        • I think it was not smoke, but steam. That’s what I saw anyway.

          There was a lot of sand in the air everywhere in the Canaries this morning, too, because of the Calima. This is a hot stormy wind from the Sahara desert.

  8. The battle for obtaining the bathymetry go on…

    Published in the FB of the Spanish Oceanic Institute, owner of the ship Margalef, 15 minutes ago:

    “IEO Sirs: Excuseme for the insistence that we have curious minds and I’m also sure that you understand us because the curiousity is the mother of science. I intend to be educated, not politically correct. Without going into the reason has changed its publication policy Bimbache operation, but without being as politically correct answers that are being cleaned bathymetry of interference from the fall of last year. I’m sure you understand our curiosity not only to know the height of the volcano, but also to see a plan elevation, bathymetry. Especially after seeing how the bathymetry of November 13 was observed as a zone volatilized 1 km long by 200 meters wide for the northern slope of canyon. We request for publication of the bathymetry as soon as possible. All people who are interested in this phenomenon and all the people who love the Cienica dissemination, we thank infinitely.”

  9. Could be! On the Moviestarcam today everything is so “vague” because it varies Sun The Utstream is standing secure. Hopefully the google translated properly.

  10. Atention. Movement of troops in the batlle for the bathymetry.

    IEO answers:

    Ieo Comunicación

    En primer lugar quisiéramos disculparnos por la falta de información en las últimas semanas. Esperamos poder publicar un nuevo informe en los próximos días.

    Queríamos también explicar que la presencia del IEO en El Hierro no responde a ningún proyecto de investigación sino que se trata de una misión para dar respuesta a un plan de emergencia por una crisis volcánica. Por tanto el objetivo primero no es investigar sino aportar información que sirva para mantener la seguridad de la población. Esto implica, entre otras cosas, que las prioridades de la investigación no las marca el IEO sino el comité científico del PEVOLCA. Por tanto, los resultados se envían en primer lugar a dicho comité y después, siempre que se considere de interés, el científico responsable del estudio lo hace público a través de un informe.

    En cuanto a las últimas batimetrías, en primer lugar no se pudieron completar por las ya comentadas interferencias. Cuando se procedió a barrer nuevamente la zona problemática el buque sufrió una pequeña avería que obligó a volver a puerto. Tras su reparación, la intención era volver a la zona para terminar los trabajos pero el PEVOLCA solicitó que el buque fuese a la zona norte para hacer una campaña de hidrografía y comprobar si había o no salida de gases en la zona de El Golfo.

    Tras comprobar que no había actividad en el norte, se procedió a completar las batimetrías en el sur y, una vez procesados los datos e informado al comité de PEVOLCA, los investigadores y el gabinete de prensa del IEO se encuentran preparando un informe para hacer público.

    Una vez más disculpen las molestias. Un saludo

    • That sounds positive – and it explains why we’ve not had a report for a while. Let’s hope the public report comes out soon.

    • First we would like to apologize for the lack of information in recent weeks. We hope to publish a new report in the coming days.

      We also wanted to explain that the presence of the IEO in El Hierro not to respond to any research projec,t but it is a mission to create an emergency plan for the volcanic crisis. Thus the primary objective is not to investigate, but to provide information to help maintain the security of the population. This implies, among other things, that the priorities of research not only for the IEO PEVOLCA scientific committee. Therefore, the results are sent first to the committee and then, if deemed useful, to the scientist responsible for study through a public report.

      As for the latest bathymetry, first it could not be completed by the already mentioned interference. When we proceeded to sweep the problem area again the ship had a small fault that forced her to return to port. After repair, the intention was to return to the area to complete the work but the PEVOLCA requested that the vessel wa sent to the north to do hydrography and check whether or not a vent existed in the area of ​​El Golfo.

      After confirming that there was no activity in the north, we proceeded to complete the bathymetry in the south and, after processing the data and informing the committee PEVOLCA, researchers and the press office of the IEO, we will prepare a public report.

      Once again sorry. Greetings!

      Sorry for any translation errors. It took me a while to hand-translate this.

  11. Well.
    It explains that the only one reason we had not reports are only political reasons.
    A volcan hidden with the magical blanket of the Lord of Rings.
    Remember that Sarmiento de Gamboa was making bathymetry in the beggining of december and on the end of december… In this case Sarmiento de Gamboa doesn´t belong to IEO. The owner of Gamboa is CSIC.
    We had not bathymetry not by technycal problems but the politicians and THE SCIENTIST TECHNICIAN thougth the bathymetry are not of general interest in their point of view of civilian defense.
    I can understand this thought from politicians but I can not understand this thought by a scientist technician.
    This event is HISTORICAL for the spanish vulcanism and the thougths of these politicians and this scientist technician were dwarf´s thoughts.
    This event has a point of view of the civil defense but this event is an HISTORICAL event in our country.

    • I would say that they are inexperienced in how to handle an eruption from a public relations standpoint. As well as they do not know enough to know what is important.
      They are not real volcanologists, they are geologists specialising in landslides mostly.

  12. I like the new SIL-station Dyngjufjöll.
    It is a wee bit on the noisy side, but it is terrific for seing what is going on in and around Bardarbunga.

    • I just made arrangements for an “Icelandic Highlands Tour” With one of my buddies with a large Land Rover. Going from the southern tip of Langjökull to askja and Kverkfjöll. Can’t wait.

      • Askja should be something I have heard.
        Krafla is also a very nice volcano. It is mind-boggling to walk around there. I visited in early june. Stark black lavas, very nice.

  13. And supposing the adage that Bob gets more active as tremor falls, we should be getting some action soon.
    The tremor dropp quickly earlier today, is usual it does not show on the other stations.
    It is remarkable hos smooth and stable it is now. And irritatingly enough, the hourly plot is deleted by IGN for the exact hour when it happened.
    Here is the 24 hour spectral plot.

    Is this correct?

    Update 16/01 – 15:12 UTC
    – A partial collapse of the vent occurred at 11:40. At 11:40, the HT was still at medium strength but the many hydromagmatic explosions were an indication that a partial or complete collapse could happen. Harmonic tremor is minimal at this moment but has a tendency to increase again.

    • Hi Judith and all,
      Sounds reasonable to me, should see tremor increasing over next few hours if BoB sticks to his usual routine, we have definately seen this before. Armand is usually pretty accurate but he has announced the end of BoB at least twice, so don’t believe him if he says that 🙂

    • No, it is totally wrong. It seems like ER has gotten it rather backwards.

      The tremoring is showing gas release and deep magmatic movement in the magma chamber(s) under Tanganasoga. They can increase and decrease totally independent of Bobs activity.
      Though, there seems to be a spatial relationship between the decrease of tremoring, and an increase in Bobs activity, this probably due to gas pressure having been built up which will push out new magma together with the gas.
      We will probably see an increase the next 24 hours at Bob, if this is true this time around, we should see the increase within a couple of hours. Activity at Bob though (17 swedish time) very low.

      Also, the last time around the cone collapsed we had the large bulge of water shooting out of the water. Nothing like that was visible this time either.
      I though think Armand et ál has confused the term “vent collapse” with “tube collapse”. There have been a couple of tube collapses happening right before Bobs vent (crater), those are always followed by a marked increase in tremoring, and a subsequent formation of a new vent slightly closer to land. A tube collapse is loose term, we are more likely talking about the tube being blocked as magma sollidifies in the tube and blocks it. Sometimes a blockage gets blown out, and sometimes a new vent is formed.
      Terminology is important when talking about these processes.

      • To be clear. What we are seeing today is gas-release stopping under Tanganasoga. With the distinct possibility that a blockage deep in the feeder was removed. We should as I said, soon see new magma entering Bob. It usually takes between 5 and 15 hours depending in the amount of gas pushing it.

      • Thanks for explaining that Carl,
        makes much more sense when you substitute tube for vent. It’s certainly a pattern we’ve seen before…

      • Carl, do you think that the magma is trying to find a new way up, under Tanganasoga? Many of the recent earthquakes seem to be pointing in that direction. And could this be a different magma chamber than the one feeding Bob, as Bob is today 99 days old marking the second longest duration for Canary Island volcanoes in historic times (which go back to 1585)?

  15. Both vents are open for business today.
    Close Bob is having a lot of degassing and pyroclasts.
    Then original Bob is pushing gas and silt further out.

  16. These questions are being asked on Avcan FB>

    Pregunta tonta: si el tremor de los sensores de Hierro muestran un bajón tan acusado a partir de las 11:40… ¿Por qué en el resto de las gráficas de las demás islas, el tremor de fondo que registran (y que se supone que es el ruido de fondo que notan de Hierro) no registran ningún tipo de cambio y están como si nada hubiera ocurrido?
    Silly question: If the tremor of iron sensors show a very sharp downturn from 11: 40… In the rest of the other islands, the tremor of background graphics that record (and is supposed to be background noise that notice of iron) do not record any type of change and are as if nothing had happened?

    Ana Sosa creo que las otras islas no reflejan el tremor de El Hierro, lo que sí aparecen muchas veces son los sismos y también se han visto reflejadas las fuertes explosiones que se han dado en El Hierro. Por eso creo que es totalmente normal que sigan mostrando el mismo patrón aunque en El Hierro haya disminuido el tremor.
    Pero lo que comentas Julia Sisi, eso sí que es una curiosa casualidad, verdad?

    I think that the other islands do not reflect the tremor of El Hierro, which appear many times are earthquakes and have also been reflected strong explosions that have occurred in El Hierro. Why I believe that it is quite normal to continue showing the same pattern but in El Hierro has decreased the tremor.

    Do but what you mention Julia Sisi, that’s a curious coincidence, really? (Translated by Bing)
