    This has got to be related to the 2 in Japan – was just thinking that there could be others around the Ring of Fire when watching the news last night.

    • Wasapilot

      Unlikely according to a geophysist friend of mine CG. terrifying event, and a 7.8 is a whole lot of enegy that has to be absorbed in the surrounding crust.

      • Crowgirl

        They do seem to happen in clusters quite frequently though

        • Just checked. No Supermoon, although we had one a week ago….

        • Wasapilot

          coincidence I think, especially seeing they are on opposite sides of the Pacific.

          These poor people will have aftershocks around mag 7, and as the main eq was only 20 something km’s deep, they will be very violent close to the epicentre. Fingers crossed for them.

          • Skydog

            There was only 3 weeks between the Christchurch Feb 2011 quake and the large quake in Japan that caused the Tsunami. Another coincidence?

            Surely if something no matter how big or small moves at one end, there must be effects at the other?

          • Wasapilot

            Very true Skydog, however the geophysics and seismology guys say that the changes in strain due to a large event are only over several hundred kilometres in distance from the epicentre.

            IIRC the change in strain on tne closest part of the Alpine fault to the Feb 2011 Christchurch EQ was theoretically close to zero.

            They do calculate this I am told, however the science is relatively young at around 50 years. So I guess it is still up for grabs as they say.

          • Also, and I say this as a layperson, I suspect the the sort of earthquake we just saw is but a minor bit of energy release on a planetary scale.

          • Orca

            I do have some knowledge in this area, and I believe that the geophysicists have it arse about face. They are trying to look at how one seismic event affects the movement of the plate. They should instead be looking at how the movement of the plate affects the seismic events around it. Of course these events are linked, the plate is moving.

          • Wasapilot

            Around 14000km from Japan to Equador, hard to imagine transfer betwenn these two locations though Orca?

            It must surely be one of the most difficult sciences I imagine.

          • Orca

            No, what I am saying is that the whole concept of “transfer” between locations is flawed. I agree that one location doesn’t affect another location at all, which is what they are saying, but its irrelevant.

            The “pacific rim of fire” refers to the surrounding edges of the pacific plate, i.e where this major tectonic plate meets the other plates around its perimeter. What these people are trying to suggest is that the pacific plate is somehow a semi-motionless object that can only be moved by the movement of other plates touching it (hence earthquakes), and that one earthquake cant move the plate enough to cause another one.

            What I am saying is that it is crazy to suggest that the pacific plate is a motionless object, and that it does move by itself, not as a result of other earthquakes, and that every time that it moves, it must affect everything around its perimeter simultaneously. When it moves, most of that energy is stored in friction between plates, but some is released in localised movement (quakes).

            So I am saying that one movement of the pacific plate, can cause several earthquakes as a result, but not all will occur simultaneously, because much of that energy is stored for release later. It is the plate movement that links the quakes around it, not the quakes that link the quakes around the plate.

  • No changes in sea level reported yet along Ecuador’s continental coastline.

  • Time in Ecuador is 8:56 PM, which makes this report from India kind of incredible…

    Clearly a file photo, a bit like the Whangarei fire truck

  • Yeah, I wouldn’t stand there if I were you.

  • It’s going to be a long night

  • So far there have been no reports of casualties, but it is hard to imagine there are none.

    The image below is reported as the damaged air traffic control tower. But again, daylight made it unlikely.

  • Reports of casualties are starting to come through, varying between 16 and 25.

    • Up to 28 now. I suspect that will keep rising for a while.

      • Ecuadorian Vice President Jorge Glas just declared at least 28 deaths

  • Coming through now. Not confirmed, but unique photo so not been used before.

      That picture reminds me of the PGC building in Chch, amazing that the lights are still on on the top floor

  • Karma

    I read this article recently about how California is overdue for a big one. Makes for pretty sobering reading.

  • AndrewML

    This is a good site if interested in earthquakes world wide, only reports on magintude 4 and above. See here. http://ds.iris.edu/seismon/eventlist/index.phtml

  • Confirmed death toll up to 41 at the moment, and expected to rise.
