ABSTRACT
The total damage caused by a tsunami is a function of two kinds of biophysical factors. First is the cause, mode of generation, location, and geological environment in which a tsunami is generated; this would determine the how and with what energy and velocity the wave train would move. Second is the bathymetry and geomorphology of the coast concerned. A variety of fundamental studies need to be made to understand the tsunami-causing processes in the Indian Ocean region:
(i) Identification and location of the possible causes and potential sites where tsunamis could be triggered. The stress map of the region, downloadable from https://www.world.stress.map.org, could be a good starting point.
