The Kermadec tsunami was generated by a Mw 7.6 earthquake (29.539°S 176.340°W ), at 19:03:18 UTC, 163 km (101 miles) E of Raoul Island, Kermadec Islands (according to the USGS). Forecast results shown below were created with the NOAA forecast method using MOST model with the tsunami source inferred from DART® data.
The graphics display 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 the scale bar.
- Model amplitudes calculated with the MOST forecast model. Filled colors show maximum computed tsunami amplitude in cm during 24 hours of wave propagation.

Comparison of the July 6, 2011 Kermadec tsunami recorded at DART 54401. 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 closest DART (54401).
