On October 25, 2010, an earthquake with a magnitude of 7.7 occurred off the western coast of Sumatra, Indonesia. This produced a localized tsunami up to 9 ft tall that struck the Mentawai Islands. It has been reported that approximately 300 people have been killed, and hundreds more are missing. This animation from NOAA shows the propagation of the tsunami.

The Indonesia tsunami event was generated by a Mw 7.7 earthquake (3.484°S, 100.114°E ), at 14:42:22 UTC, 240 km (150 miles) W of Bengkulu, Sumatra, Indonesia (according to the USGS). In a little under 2 hours, the tsunami was first recorded at DART® buoy 56001 and in a little under 3 hours, the tsunami was recorded at DART® buoy 56003. Forecast results shown below were created with the NOAA forecast method using MOST model with the tsunami source inferred from DART® data. The tsunami waves first arrived at Padang (approximately 270 Km from the earthquake epicenter ), at 15:47 UTC, about 65 minutes after the earthquake. The DART data and model inversion indicate that the tsunami may be larger than the earthquake magnitude of 7.7 suggests.
