Comparison of the February 27, 2010 Chilean tsunami recorded at sea-level gauges along U.S. coastlines with forecasts obtained from high-resolution forecast model runs. The forecast models were run in real time before the tsunami reached the locations shown. The model data for Hawaii and the U.S. West Coast show 9 minute early arrival (0.8-1% error accumulated during the propagation simulation). The plots show model data for those locations shifted 9 minutes later for the comparison purposes. (see References, below)
