“Study on Progressive Collapse Analysis for Tsunami Hazards”

Abstract

A tsunami can be defined as a series of waves with a long wavelength and period (time between crests) usually
generated by disturbances associated with earthquakes, landslides, volcanoes eruptions or meteor impact occurring
below or near the ocean floor. In simple words Tsunami is a combination of two words derived from the Japanese
language the characters "tsu" meaning harbor and "nami" meaning wave. Or in other words tsunami is the water waves
which are generally caused by the submarine earthquakes. They are generally rare event but they cause terrible damage
to life as well as to property. The occurrence of tsunami (like the one during Indian Ocean tsunami on December 26,
2004, the Sumatra earthquake in 2004 or the one during the Tohoku earthquake in Japan in 2011) caused devastating
damages to the coastal structures and tremendous casualties. And in most of the cases the tsunamis are induced due to
Earthquake forces hence it is necessary that coastal structures should be designed against both earthquake and
tsunamis. This paper deals with the hazards associated with the earthquake forces and the tsunamis triggered due to
these forces. Also extensive literature session is done to come to conclusions about the structures along the shorelines
and coast. Also an attempt has been made in this paper for the future scope of work in this area.
