The island, like many others in the Nicobar and Andaman islands, was severely affected by tsunamis generated by the 2004 Indian Ocean earthquake. According to reports from the Andaman and Nicobar Inspector General of Police, S.B. Deol, the Nancowry group of islands were among the worst-hit islands in the chain, with thousands missing and presumed dead. Post-tsunami satellite photos, and government situation reports indicate that while portions of Nancowry Island were affected, the adjoining islands of Katchall and Kamorta were more severely overrun. As of January 18, 2005, the government reported only 1 dead and 3 missing from Nancowry island, but 51 dead and 387 missing from Kamorta, and 345 dead and 4310 missing from Katchall.
