A new method for real-time tsunami forecasting will provide NOAA’s Tsunami Warning Centers with forecast guidance tools during an actual tsunami event. PMEL has developed the methodology of combining real-time data from tsunameters with numerical model estimates to provide site- and...

A method is derived to forecast theextreme heights of later waves in Pacific-widetsunamis, for locations in the vicinity of real-timereporting tide gages. The forecast for wave peaks hasthe form η<Subscript>F</Subscript>(t)=η<Subscript>B</Subscript>(t) + η<Subscript>e</Subscript>(t),where η<Subscript>e</Subscript>=Aσ exp [- (t - t<Subscript>o</Subscript>)/τ ].
