Main Event Page

Model and Data Comparison Plots

The Northern Sumatra, Indonesia tsunami was generated by a Mw 7.8 earthquake (2.360°N, 97.132°E ), at 22:15:02 UTC, 200 km (125 miles) WNW of Sibolga, Sumatra, Indonesia (according to the USGS). In a little under 2 hours, the tsunami was first recorded at DART® buoy 23401 and in a little over 3 hours, the tsunami was recorded at DART® buoy 56001. 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 Telukdalam (approximately 215 km southeast from the earthquake epicenter ), at 22:55 UTC, about 40 minutes after the earthquake.

The graphics to the left display 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 the scale bar.
