Regional tsunami hazard assessment for communities on the Kenai Peninsula, Alaska

Metadata Updated: November 10, 2020

We assess potential tsunami hazard for three coastal communities on the Kenai Peninsula, Alaska: Anchor Point, Nanwalek, and Port Graham. The primary tsunami hazard for these communities is considered to be near-field, with a major threat originating from tsunamigenic earthquakes along the Alaska-Aleutian megathrust. We numerically model tsunamis generated by three different megathrust earthquakes and two volcanic sources, analyze tsunami wave dynamics, and develop approximate tsunami hazard maps for the communities. The hypothetical tsunami scenarios that we examined simulate Mw 9.0 megathrust earthquakes with a slip distribution in the 5-35 km (3-22 mi) depth range along the Alaska-Aleutian megathrust, as well as tsunamigenic mass flows originating from Augustine Volcano. The maximum runup heights are 12.2 m (40 ft) in Anchor Point, 14 m (46 ft) in Nanwalek, and 14.9 m (49 ft) in Port Graham. Results presented here are intended to provide guidance to local emergency management agencies in initial tsunami inundation assessment, evacuation planning, and public education for mitigation of future tsunami hazards.

Guid
Access Constraints Use Constraints: This dataset includes results of numerical modeling of earthquake-generated tsunami waves for a specific community. Modeling was completed using the best information and tsunami modeling software available at the time of analysis. They are numerical solutions and, while they are believed to be accurate, their ultimate accuracy during an actual tsunami will depend on the specifics of earth deformations, on-land construction, tide level, and other parameters at the time of the tsunami. Actual areas of inundation may differ from areas shown in this dataset. Landslide tsunami sources may not be included in the modeling due to unknown potential impact of such events on a given community; please refer to accompanying report for more information on tsunami sources used for this study. The limits of inundation shown should only be used as a general guideline for emergency planning and response action in the event of a major tsunamigenic earthquake. These results are not intended for any other use, including land-use regulation or actuarial purposes.
