Main Event Page
The Indian Ocean tsunami was generated by a Mw 9.1 earthquake (3.295°N 95.982°E), 2004-12-26 00:58:53 UTC, off the west coast of northern Sumatra (according to the USGS). Forecast results shown below were created with the NOAA forecast method using MOST model with the tsunami source inferred from tsunameter/DART® data.
