The Guerrero tsunami was generated by a Mw 7.2 earthquake (17.552°N 100.816°W), 2014-04-18 14:27:26 UTC, 36km (22mi) NNW of Tecpan de Galeana, Mexico (according to the USGS). In approximately 48 minutes, the tsunami was first recorded at tsunameter/DART® buoy 43412. 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 DART 43412 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 18, 2014 Guerrero tsunami recorded at tsunameter/DARTs 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.

Disclaimer: The forecasts on these pages show the results of ongoing research to enhance tsunami science and to improve NOAA operational tsunami forecasts. These products were developed during or shortly after the tsunami event, are intended for research use, and are not an official forecast. They should not be used as the basis of any public or private policy decisions. Please contact NCTR to find if there are more detailed follow-on analysis results.
