Sheepy Dalek, a friday riddle for your entertainment

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!

    • 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.

  1. 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.

      • 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.

    • 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).

  2. 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 🙂

    • 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?

  3. Another 3.0 mag as expected. A few more to come when they ccatch up too I think.

  4. Another 3.8, getting bigger as it goes on!

    • 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 ?

  5. 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.

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

    • OOPS. you are right luisport, postpone bedtime yet again. *Yawn* I will give it 1 hour more maybe. Hard to tear oneself away.

    • Looked like that showed Bob’s old cone at just above 100 metres depth. No sign of any degassing or other activity though.

  7. 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

  8. 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.

      • 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

  9. 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.

  10. 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

  11. And now one for the hard core Geo people.

    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 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.
