This report will provide guidance to local emergency managers in tsunami hazard assessment. We used a numerical modeling method to estimate the extent of inundation by tsunami waves generated from earthquake and landslide sources. Our tsunami scenarios included a repeat of the tsunami of the 1964 Great Alaska Earthquake, as well as tsunami waves generated by two hypothetical Yakataga Gap earthquakes in northeastern Gulf of Alaska, hypothetical earthquakes in Prince William Sound and Kodiak asperities of the 1964 rupture, and local underwater landslides in Resurrection Bay. Results of numerical modeling combined with historical observations in the region are intended to help local emergency officials with evacuation planning and public education for reducing future tsunami risk.

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.

The final, highest resolution grid of the northern Resurrection Bay, where the inundation extent was calculated, has a spacing of 15 meters. Although the location of the inundation line has an accuracy of approximately plus or minus 15 m horizontally relative to the grid spacing, the true location accuracy is unknown, because of the complex modeling process the accuracy depends on many factors. These factors include correctness of the earthquake source model, accuracy of the bathymetric and topographic data, soil compaction in areas of unconsolidated deposits and the adequacy of the numerical model in representing the generation, propagation, and run-up of tsunami waves. Actual areas inundated will depend on specifics of earth deformations, on-land construction, and tide level, and may differ from areas shown on the map. The limits of inundation shown should only be used as a guideline for emergency planning and response action. The information is intended to permit state and local agencies to plan emergency evacuation and tsunami response actions in the event of a major tsunamigenic event. These files are not intended for land-use regulation, property valuation, or any use other than the stated purpose. Users should review the accompanying report, particularly the Sources of Errors and Uncertainties section, for a detailed discussion of limitations of the methods used to generate the various inundation models. Logical_Consistency_Report: Results of numerical modeling were verified by simulating historic tsunamis. Inundation lines are visually inspected using GIS software for identification of anomalous elevations or data inconsistencies. See text report for detailed explanation of the tests used to determine the fidelity among the various data sources that were used to generate this dataset. Completeness_Report: The dataset contains tsunami inundation limits for 4 tectonic and 3 landslide source scenarios, the 1964 observed inundation limit, and the composite maximum extent of inundation. The inundation limits are results of numerical modeling of tsunami waves with the use of shallow water equations. We conducted all hypothetical model runs using bathymetric data that correspond to Mean High Water so that the resulting maximum inundation line represents a maximum credible scenario of tsunami occurrence at high tide. The model does not take into account the periodical change of sea level due to tides, but it does include the effect of local uplift or subsidence during the earthquake. The data used to calculate the potential extent of tsunami inundation includes: high-resolution topography and bathymetry of Resurrection Bay, historic records of the 1964 inundation line at Seward, historic seismicity measurements, pre- and post-1964 bathymetry difference map of Resurrection Bay, and related tectonic geometry. The northern part of Resurrection Bay has been studied in great detail and we feel that the density of available information is sufficient to allow for confidence in our interpretations of likely extents of tsunami inundation. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The extent of tsunami inundation in Seward was calculated through numerical modeling of water waves over realistic bathymetry and topography. The input data for the tsunami model includes the combined topographic and bathymetric DEM of 15-m resolution described in the USGS Digital Data Series 374, "Combined High-Resolution LIDAR Topography and Multibeam Bathymetry for Northern Resurrection Bay, Seward, Alaska," by Keith A. Labay and Peter J. Haeussler. According to the corresponding metadata file, the horizontal accuracy of this DEM has not been tested. We conducted all model runs using bathymetric data that correspond to Mean High Water (MHW), with the exception of numerical modeling of the 1964 tsunami for the purpose of model validation. Those runs were conducted using the stage of tide at the time of the earthquake, approximately Mean Low Water.

These grids of increasing resolution allow us to propagate waves generated by both distant and local sources to Resurrection Bay. These grids of increasing resolution allowed us to propagate waves generated by both distant and local sources to Passage Canal. In order to propagate a wave from its source to various coastal locations we used embedded grids, placing a large, coarse grid in deep water and coupling it with smaller, finer grids in shallow water areas. See Methodology and data section of this report for more detail and additional data source information. Source_Used_Citation_Abbreviation: Labay, K.A. and Haeussler, P.J., 2008 Process_Date: 2009 Process_Step: Process_Description: Model validation - The numerical model that was used for simulation of tsunami wave propagation and runup was validated through a set of analytical benchmarks, and tested against laboratory data. The model solves nonlinear shallow water equations using a finite-difference method on a staggered grid. See Methodology and data section of this report for more detail and additional model information. Source_Used_Citation_Abbreviation: Nicolsky, D.J and others, 2011 Process_Date: 2009 Process_Step: Process_Description: Model verification - We performed the verification of the numerical model using observations of the 1964 tsunami. We compared results of inundation modeling in Resurrection Bay with observations collected shortly after the event. First, we simulated tsunami waves generated by multiple submarine slope failures using a numerical model of a viscous slide coupled with a numerical model for water waves. Then, we simulated the tectonic tsunami in Resurrection Bay using an output of a coseismic deformation model of the 1964 earthquake as an initial condition for water waves. The composite inundation zone was compared with the observed extent of inundation in Seward and at the head of Resurrection Bay. See Methodology and data and Modeling results sections of this report for more detail and additional model information.

Numerical results for each scenario include extent of inundation, sea level and velocity time series, tsunami flow depth and maximum drag force. See "Modeling results" section of this report for more detail and additional information. Process_Date: 2009 Process_Step: Process_Description: Compilation of maximum inundation zone and maximum flow depths - We calculated maximum composite extent of potential inundation by combining the maximum calculated inundation extents of all scenarios. The same method was used for calculation of maximum flow depths over dry land. See Modeling results section of the associated manuscript for more detail and additional information. Process_Date: 2010 Process_Step: Process_Description: Calculation of the potential inundation lines - For each grid cell in the high-resolution DEM, we found whether this cell was inundated by waves or stayed dry through out the entire simulation. Then, we defined a function that provides a value that is equal to one at the center of each wet cell and is equal to negative one at the center of each dry cell. Using a linear interpolation algorithm in Matlab, we plotted a zero-value contour that delineates dry and wet cells from each other. The contour line was then directly exported to the ArcGIS in the WGS84 datum.
