2004 Indian Ocean Tsunami Reshapes Tsunami Science

The Indian Ocean tsunami of December 26, 2004, triggered by a massive 9.1 magnitude earthquake off Sumatra, resulted in over 227,000 deaths and widespread devastation across 17 countries, highlighting significant gaps in tsunami preparedness and response. In the aftermath, advancements in tsunami science have led to improved early warning systems and disaster risk reduction strategies, reshaping how communities respond to such catastrophes. However, the disaster had lasting impacts on local fishing practices, particularly in Kanyakumari district, where traditional shore-netting has declined due to coastal erosion and changes in marine life. Survivors like S Rajasekar and Karishma, born after the tsunami, navigate their identities amid the memories of loss and trauma experienced by their families. Personal accounts detail the immediate chaos of the tsunami as well as ongoing struggles faced by those affected, underscoring the long-term psychological and societal effects of the disaster. As communities continue to rebuild and adapt, the lessons from this tragedy remain critical for future preparedness efforts.
