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.

The graphics display research forecast results, showing qualitative and quantitative information about the tsunami, including tsunami wave interaction with ocean floor bathymetric features, and neighboring coastlines. Tsunami model amplitude information is shown color-coded according to the scale bar. See information on MOST model.
