Submersible surveys of the ocean floor where the December 2004 Sumatra tsunami originated show it is devoid of life.

From the Sydney Morning Herald "Shocked scientists find tsunami legacy: a dead sea"
A "DEAD zone" devoid of life has been discovered at the epicentre of last year's tsunami four kilometres beneath the surface of the Indian Ocean.
Scientists taking part in a worldwide marine survey made an 11-hour dive at the site five months after the disaster.
They were shocked to find no sign of life around the epicentre, which opened up a 1000-metre chasm on the ocean floor.
Instead, there was nothing but eerie emptiness. The powerful lights of the scientists' submersible vehicle, piercing through the darkness, showed no trace of anything living.
The south Asian tsunami claimed more than 270,000 lives and created one of the largest relief efforts in recent history. A year later, the "fast acting" UN is having its second meeting on setting up a regional tsunami warning system. Gallery of tsunami photo can be found here.
Some scientists think that a US east coast mega tsunami is possible. Maybe someday the US eastern seaboard could its own tsunami warning system.
