    Thanks! We really need buoys near the rims of submarine calderas. They may save thousands or even tens of thousands of lives in the future!
    Some other submarine volcanoes appear to have trapdoor calderas. The possible source of one of the 1808 mystery eruptions (as postulated by Geology Hub), Submarine Volcano 1 in Tonga appears to have had a trapdoor caldera collapse.

  • @LadyAnuB
    @LadyAnuB ปีที่แล้ว +12

    Can just one side moving upward suddenly generate a tsunami or do you need the whole structure to go up on one side and down on the opposite side?
    I would think the new channel member you have in this video's name is pronounced ren-nay

    • @brianorca
      @brianorca 11 หลายเดือนก่อน +9

      One side up and one side down is what keeps the chamber volume the same while still allowing rapid movement. If there was rapid movement that was only up or only down, it would probably involve an actual eruption, or a chamber collapse, which would involve a much larger seismic event.

      @dr.floridaman4805 11 หลายเดือนก่อน

      if you don't know the answer just speculate. let the blind lead the blind.
      any displacement of water will cause a tsunami. glaciers can cause tsunamis. no tectonic plates involved.

    • @dananorth895
      @dananorth895 11 หลายเดือนก่อน +3

      If only one side slipped, you'd have a volumetric dislocation of water producing a tsunami. But the othe side did the same only opposite movement. So doubling the total effect.

    Wow, science is really cool. This is one of those explanations of a natural phenomenon that I never would have even thought of on my own, but explained like this, it seems so obvious that something like that could occur!
    I wonder if trapdoor quakes have a distinctive two-peaked seismic signal due to the waves first arriving from the close rupture half, then from the far rupture half - if that was the case, it could be theoretically possible to detect them in a few cases with existing instruments/data, albeit with a pretty high false negative rate.

    OT, pls could you teach us what is a 'sill' sp? Of all my Volcano watching I do mot believe I heard that term used. Likely internal formation ? But I would appreciate knowing.
    Imo seems a lot of tense anticipation abt Svartsengi, I realised could just as easily calm. I don't know if I should be ashamed of being a magma junkie or not? But I do like Mother Earth reminding who is in Charge.

    • @whiteknightcat
      @whiteknightcat ปีที่แล้ว +4

      A sill is a horizontal magma intrusion, where it spreads sideways underground. This is as opposed to a dike which is a vertical intrusion. This is illustrated at 2:40 in the video - the various wide spots on the vertical magma intrusions are sills.

      @whiteknightcat 11 หลายเดือนก่อน

      @@spocksdaughter9641 Predictivity is way beyond my scope of knowledge, however it is hypothesized that sill formation is what has led to the delay in an eruption from the Blue Lagoon area. The force that would have been directed upwards toward the surface is now being directed horizontally in sill formation. As for the sizes of such bodies, I think that can only be estimated from seismic data.
