: Listen to the Honshu earthquake & Historical Japan Tsunami
The Honshu, Japan tsunami was generated by a Mw 9.0 earthquake (38.297°N 142.373°E ), at 05:46:24 UTC, 130 km (80 miles) E of Sendai, Honshu, Japan (according to the USGS). In approximately 25 minutes, the tsunami was first recorded at DART® buoy 21418. Forecast results shown below were created with the NOAA forecast method using MOST model with the tsunami source inferred from DART® data.
The graphics 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.
Model and DART® buoy data / tide gage data comparison
- Comparison of the March 11, 2011 Honshu tsunami recorded at DARTs and sea-level gages in the Pacific and along U.S. coastlines with model forecasts. The DART model timeseries are obtained from the pre-computed generation/propagation forecast database in real time, after fitting models to tsunami records from two closest DARTs (21418 and 21401). The flooding forecast models (high-resolution inundation models for coastal locations) were run in real time before the tsunami reached the locations shown. The model data for Hawaii, the U.S. West Coast and South America show 3 to 15 minute early arrival (less than 2.5% error accumulated during the propagation simulation). The plots show model data for those locations with time shifted later for comparison purposes. (see References, below).
