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. |
