Would a tsunami kill you instantly?

No. Because of their long wavelength, tsunamis act as shallow water waves. So no matter how far down you dive, you’ll still be caught in approximately* the same wave-induced current that will sweep you into deadly collisions with structures, debris, etc.

Warning criteria

That warning, he says, can go out within three to five minutes of the undersea earthquake and gives an early indication of its potential to cause a tsunami which may do damage. “If the earthquake is big it could be moving quite a lot of sea floor — often along a subduction zone”, he explains.

How far would a 1000 foot tsunami travel?

Flooding can extend inland by 300 meters (~1000 feet) or more, covering large expanses of land with water and debris. Inundation distances can vary greatly along the shorelines, depending on the intensity of the tsunami waves, the undersea features, and the land topographic elevations.
