Local Valparaiso Modeling Results | Web Link Compilation | Model Data Comparison Plots

The Chile tsunami was generated by a Mw 8.8 earthquake (36.122°S 72.898°W ), at 06:34:11 UTC, 115 km (60 miles) NNE of Concepcion, Chile (according to the USGS). In approximately 3 hours, the tsunami was first recorded at DART® buoy 32412. 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 Valparaiso, Chile (approximately 330 km northeast from earthquake epicenter ), at 0708UTC, about 34 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.
