    Does anyone have any scientific facts that during tsunami, ocean is probably the safest place on earth?

    I have no facts. I would GUESS it would be somewhat safer to be diving in mid ocean 100' below the surface when a Tsunami comes, as compared to standing at the the low tide shore mark waiting for it to come ashore. I am positive the safest place on Earth to be would be anywhere on land that the Tsunami cannot reach.

    Divers were below during the one (I believe it was divers in Indonesia) that hit a few years back.

    They described it as a quick surge of a few meters. I never found out- but I wonder if the home base of the boat's dive op was still standing. :idk:

    The real damage occurs in the shallows where "ground swell" comes into play.

    Safest place? How about Mile High Stadium in Denver? (I think base camp at Everest has some sanitation issues and risk of altitude sickness.)

    As Roatanman said, there were divers in the water--I read about some in the Maldives who got quite a ride. It depends on the amplitude of the wave that passes over you, which depends, to an extent, on the topography of the ocean floor. A devastating tsunami might only have an amplitude of 30 centimeters or less in deep open water and it is only when it reaches shallower water that it gains amplitude. So a kayak in mid-ocean might be safe, blue-water diving might be safe, beach diving, not so safe.

    Edit: From Undercurrent, accounts from divers in the Boxing Day tsunami (emphasis added):

    I would rather be on a mountain during a tsunami.

    I think that they're saying the safest place to be and still experience the wave, not the safest place to be, period.

    The article states:

    "...gobbling up homes and boats and people, pulling them all back into the Indian Ocean and then flinging them back at the town again and again, killing hundreds."

    I wonder exactly how far the debris is pulled out into the ocean. It would seems that if the situation was right (a wall dive where the shelf is relatively close to the shore) you could start to see parts of houses, or a fleet of tuk-tuks come raining down on you. Terrifying and surreal.
