How a tsunami works

Check out this link.

It has links to more tsunami footage, animations of the Bandeh Aceh shoreline from before to after tsunami, explanations of how tsunamis work, and other uh, fun stuff.

They have a page called Anatomy of a Wave, and that has a bunch of interesting information.

Like a normal wind-generated wave has a speed of 8 to 100 kilometres per hour (5-60 miles per hour), while a tsunami wave travels at a speed of 800 to 1000 kilometres per hour (500-600 miles per hour.) But if a difference.

From this page:

A tsunami is even capable of reaching sheltered areas due to varying land features and the underlying seascape. For instance, a protected bay area with a narrow inlet can give a tsunami a "funnel" to travel through, amplifying the destructive power of the waves. Also, a river channel can provide room for a tsunami bore to rush through, allowing it to flood tremendous tracts of land.

And that’s precisely what happened along the south coast of Sri Lanka. Some villages up river from the ocean were flooded and devasted along the banks of the river.
