2012 Indian Ocean earthquakes

The mainshock struck at 08:38:36 UTC, 15:38:36 WIB, on 11 April 2012, with its epicentre in the Wharton Basin about 430 km southwest of Banda Aceh in Indonesia's Aceh province. It was a strike-slip undersea event, and an Mw 8.2 aftershock followed at 10:43 UTC, roughly two hours later. Small tsunamis with peak amplitudes up to 107 cm were recorded near the epicentres, and structural damage was limited by the offshore location and the depth.
