Question

safe construction practiies of tsunami

Answer 1

Tsunamis result due to vertical movement of the sea floor due to tectonic causes and result in vertical displacement of the overlying water column. This produces gigantic waves which travel at about 800 kmph and hits the coast as a wall of water destroying everything in its path. Tsunami wavers may be amplified by bathymetric features, making its height vary from coast to coast. The most recent and devastating tsunami that hit the Indian coast on 26 December 2004 led to a loss of 9395 lives and affecting 26.63 lakh people. The east and west coast of India and the island regions are vulnerable to tsunamis potentially generated by the subduction zone movement in Andaman-Nicobar-Sumatra Island Arc and the Makran area north of Arabian Sea.


Tsunami Safety Rules. A strong earthquake felt in a low-lying coastal area is a natural warning of possible, immediate danger. Keep calm and quickly move to higher ground away from the coast. ... When you hear that an earthquake has occurred under the ocean or coastline regions, prepare for a tsunami emergency.
