The field excursion focuses on understanding the geological and tectonic dynamics of the Andaman and Nicobar Islands, which lie along the seismically active Sumatra Andaman subduction zone. The trip will cover key locations such as Siri Vijaya Puram (Port Blair), Mithakhadi, Collinpur, and Shaheed Dweep (Neil Island)—sites that display clear signatures of coseismic uplift and subsidence caused by the recent 2004 and past seismic events. The excursion shall showcase near shore shallow coastal stratigraphy, marine terraces, and other geomorphic features to interpret the history of the past earthquakes and tsunamis, including those related to the 2004 Sumatra-Andaman earthquake. The presence of beachridge-swale, sea notches, dead forests, and tsunami deposits will help understanding land level changes and tsunami impacts in the region.
