ate landslide sites near large bodies of water. The staff should confirm that the possible tsunamigenic sources due to volcanic activity have been considered in the application’s tsunami assessment, including pyroclastic flows, submarine caldera collapse, explosions, and debris avalanches or flank failures. The staff reviews the initial (impulsive) displacement of the water surface at the generating source that subsequently causes the radiating tsunami waves. The staff should confirm that the initial displacement of the water surface is estimated conservatively in the application. 3. Tsunami Propagation Models. The staff reviews the licensee’s evaluation of tsunami propagation to the site. If the licensee used tsunami propagation models for the tsunami hazard analysis, the staff also needs to review them. Staff must confirm that the models selected by the applicant are similar, in terms of details and accuracy, to the ones used by recognized federal agencies such as NOAA, the U.S. Geological Survey (USGS), and the U.S. Army Corps of Engineers (USACE), to name a few. The staff should confirm that numerical models selected by the applicant are well accepted in the scientific communities through publications in peer-reviewed literature, or having received verification through testing and validation through widespread use. The staff reviews the model parameters and other input data used to simulate the propagation of tsunami waves towards the site. The staff should confirm that the values of the model parameters selected by the applicant for its computer simulations are adequately described; conservative parameter values should be used if the model was not calibrated with known historical events. Staff should confirm that all other data sources used in the computer simulations are identified and described in the application. The staff need to review bathymetric and topographic data used in the numerical models. The staff reviews propagation of the tsunami waves from
