This data release contains postprocessed model output from a simulation of hypothetical rapid motion of landslides, subsequent wave generation, and wave propagation. A simulated displacement wave was generated by rapid motion of unstable material into Barry Arm fjord. We consider the wave propagation in Harriman Fjord and Barry Arm, western Prince William Sound (area of interest and place names depicted in Figure 1). We consider only the largest wave-generating scenario presented by Barnhart and others (2021a, 2021b). As in Barnhart and others (2021c), we used a simulation setup similar to Barnhart and others (2021a, 2021b), but our results differ because we used different topography and bathymetry datasets. We used datasets that supported refinement of the model to a 5-meter resolution along the shorelines. This data release contains GIS files and geographically registered figures representing the maximum wave height and extent of simulated inundation along shorelines. This data release does not include simulation results related to other related phenomena (for example, current strength or the interaction of the wave with glaciers).
