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.
An example of such an architecture is where a laminar flow around a building will protect the walls. The structure can also rest on a hollow masonry block that for example can hold a body of water to sustain a family. A design can include battered walls, cantilever steps and a wooden superstructure with the walls jutting out. Bamboo ply panels can be added to cover the sides.
A structure like this, concomitant with its mechanical strength, will provide its occupants with independent potable water storage for an extended period of time. The first example known has been constructed at Poovar Island in southern Kerala, India.
