Tsunami News & Photos

All this talk about the various seismology stations around the world not giving any warning about the Tsunami, is very true, for the very simple reason that it would not have been known if the earthquake had produced a tsunami as the seismic recordings can't supply that information

In the Pacific it is up to 3 hours after an earthquake (depending on location) before the seafloor sensors can confirm that a tsunami has been produced by the quake. It is only when information from the seafloor sensors is analysed that a tsunami warning will be issued if required. Tsunami warnings are not issued on Earthquake evidence alone. Any network in the Indian Ocean would need to be very quick acting due to the smaller size of the ocean compared with the pacific and I would think require more sensors than used in the Pacific.

I should say we could do with a Tsunami network in the Atlantic Ocean as well. They do occur in the Atlantic and as mentioned earlier also in the North Sea.
