Can a building withstand a tsunami?

A tsunami-proof building is a purposefully designed building which will, through its design integrity, withstand and survive the forces of a tsunami wave or extreme storm surge. It is hydrodynamically shaped to offer protection from high waves.

How long after an earthquake does a tsunami hit?

As the estimated time of the tsunami waves to reach the coast is 30 minutes after the earthquake, the community should go to the vertical or horizontal evacuation in less than 30 minutes.
