    Addendum A: Regional tsunami hazard assessment for Pasagshak, Alaska

    Metadata Updated: July 5, 2023

    Report of Investigation 2019-6A, Addendum A: Regional tsunami hazard assessment for Pasagshak, Alaska, provides an estimated extent of the tsunami hazard zone in the community of Pasagshak, Alaska. Pasagshak is a small community on Kodiak Island, about 70 km (44 mi) south of Kodiak. The highest resolution bathymetric grid that covers this community is the level 3 grid with a grid size of about 45x82 m. We estimate the extent of the tsunami hazard zone in Pasagshak by running all nine tsunami scenarios described in the main report (Report of Investigation 2019-6). Each model run was performed for 12 hours of tsunami propagation to account for all waves in the wave train, including any secondary (reflected) waves. The maximum value of the tsunami height based on a composite of all scenarios, multiplied by a safety factor of 1.3, results in a maximum estimated runup height of 39 m (128 ft) for the community of Pasagshak. We illustrate the maximum estimated tsunami runup on land by drawing an elevation contour on the 5-m (16-ft) resolution community topographic map that corresponds to the maximum modeled wave height offshore. The complete report and digital data are available from the DGGS website: http://doi.org/10.14509/30763.

    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.
