Content:
. Potential tsunamigenic sources from both near field and far field B. Tsunamigenic source mechanisms including earthquakes that occur near or beneath the ocean, subaerial or submarine landslides, and volcanoes C. Characteristics of tsunamigenic sources i. Earthquake source parameters, including magnitude, focal depth, fault dimension and orientation, and displacement; volume and dynamics of landslides; potential landslide sources in land and submarine; and their volcanic explosions and resulting pyroclastic flows, caldera collapses and flank failures; etc. ii. Efficiency of tsunami generation iii. Maximum initial displacement of the free surface, at the respective tsunamigenic source locations D. Propagation of tsunami waves i. Propagation in deep waters (linear wave dynamics) ii. Propagation in shallow waters (nonlinear wave dynamics) 3. Tsunami Propagation Models A. The staff reviews tsunami wave propagation model(s) and model parameters used to simulate the tsunami wave propagation from the source toward the site. 2.4.6-4 Revision 4 - September 2018 B. The staff reviews input data, including bathymetry and topography data, bottom roughness, used in tsunami wave propagation model(s). C. The staff reviews the licensee’s justification for the geologic (physical) mechanism and location of its preferred tsunami generating source. 4. Wave Runup, Inundation, and Drawdown. The staff reviews the estimated wave elevation generated by the applicant’s tsunami computer simulation(s). Water wave elevations may be reported to the nearest tenth of a foot. Staff should confirm that the geodetic reference datum used by the applicant to report the water surface elevation is specified in the application. The staff’s review of the applicant’s analysis should include consideration of the entire flood event duration along with the water surface elevation estimate. The extent and duration of wave runup during the inundation phase of the flooding event should be reviewed by
