Real-time tsunami warning in the nearfield is considerably more difficult than producing warnings for distant events. Although in some cases strong shaking will provide the only warning, there are several situations in which better early tsunami warning systems could be critical. We discuss some of the issues that arise, ...

GeoClaw Model Tsunamis Compared to Tide Gauge Results Final Report
The purpose of this project is to compare GeoClaw tsunami model results to detided tide gauge results at multiple destinations for each of several tsunamis. In particular, we are interested in the suitability of GeoClaw for calculating tsunami amplitudes with enough precision to be used for forecasting, especially in the ...
