Main Event Page

Queen Charlote Island Event page | Model-Data comparisons

The Queen Charlotte Islands (Haida Gwaii), British Columbia tsunami was generated by a Mw 7.8 earthquake (52.788°N 132.101°W ), at 2012-10-28 03:04:08 UTC, 202km (126mi) SSW of Prince Rupert, Canada (according to the USGS). In approximately 45 minutes, the tsunami was first recorded at tsunameter/DART® buoy 46419. 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 the scale bar. Offshore tsunami wave amplitude was forecasted based on actual tsunami observations at DART 46419 and was not based on any particular earthquake mechanism.

Modeling Results

Model and tsunameter/DART® buoy data / tide gauge data comparison

Comparison of the October 27, 2012 Queen Charlotte Island tsunami recorded at tsunameter/DARTs and sea-level gauges with model forecasts.

The DART model timeseries are obtained from the pre-computed generation/propagation forecast database in real time, after fitting models to tsunami records from the closest DART (46419).
