26 December 2004 Tsunami
On 26 December 2004, the coast of the Nicobar Islands was devastated by a 10–15 m high tsunami following the 2004 Indian Ocean earthquake. At least 6,000 people (possibly a conservative estimate) were killed on the Andaman and Nicobar Islands during the disaster. Reports put the death toll on Katchal Island alone at 4,600. Several islands were heavily damaged with initial reports of islands broken in two or three pieces and coral reefs moved above water. Teressa Island was said to have been split into two pieces and Trinkat Island into three pieces. Some estimates said that the islands were moved as much as 100 feet (30 m) by the earthquake and tilted.
Indira Point subsided 4.25 m in the 26 December 2004 tsunami and the lighthouse there was damaged. The lighthouse has been made functional since then.
On 24 July 2005, a strong earthquake, measuring 7.2 on the Richter scale, struck the Nicobar Islands but there was no immediate report of death or destruction.
On 10 November 2009, a strong earthquake, measuring 6.0 on the Richter Scale, struck the Nicobar Islands.
On 12 June 2010, at 19:26:50 UT (Sunday, June 13, 2010 01:26:50 AM at epicenter), a strong earthquake, magnitude 7.7, struck 153 km (95 mi) west of Mohean, Nicobar Islands (epicenter: 7.748N, 91.938E).
