On 26th December 2004, a mega-earthquake with magnitude 9.3 occurred in the Sumatra-Andaman region, resulting in a large coseismic rupture and a giant tsunami that took more than 250,000 lives.
A natural catastrophe of this scale led to the Ministry of Earth Sciences (MoES) and the Indian National Centre of Ocean Information Services (INCOIS) realizing the significance of understanding the recurrence pattern of such giant tsunamis and their effects along the Indian coastline.
They realized that knowledge of these patterns can help us plan our strategies towards better mitigation plans, in urban planning along the coastline, in preparing inundation maps or tsunami hazard maps considering different earthquakes (i.e., mega and large earthquakes and associated tsunamis) and their effects along the Andaman & Nicobar coastlines as well as the east coast of Indian mainland.
Prof. Javed Malik from IIT Kanpur had experience in identifying the signature of ancient tsunamis preserved in coasta
