Iquique, Chile Event Page | Model and Data Comparison Plots

The Chile tsunami was generated by a Mw 8.2 earthquake (19.642°S 70.817°W), 2014-04-01 23:46:46 UTC, 95km (59mi) NW of Iquique, Chile (according to the USGS). The tsunami was detected and measured at the first DART (Chilean) about half an hour after the earthquake. 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. Offshore tsunami wave amplitude was estimated based on actual tsunami observations at DARTs 32402 and 32412 and was not based on any particular earthquake mechanism.

Modeling Results

Model and DART® buoy data/ tide gauge sea level data comparisons

Comparison of the April 1, 2014 Chile tsunami recorded at tsunameter/DARTs and tide gauges with model results. The DART model time series are obtained from the pre-computed generation/propagation forecast database in real time, after fitting models to tsunami records from the DARTs.
