We numerically model the extent of inundation due to tsunami waves generated from earthquake and landslide sources. Tsunami scenarios include a repeat of the tsunami triggered by the 1964 Great Alaska Earthquake, as well as tsunami waves generated by a hypothetically extended 1964 rupture, a hypothetical Cascadia megathrust earthquake, hypothetical earthquakes in Prince William Sound, and Kodiak asperities of the 1964 rupture. Local underwater landslide and rockslide events in Passage Canal are also considered as credible tsunamigenic scenarios. Results of numerical modeling combined with historical observations in the region are intended to provide guidance to local emergency management agencies in tsunami hazard assessment, evacuation planning, and public education for reducing future tsunami damage.\nThe purpose of this study is to evaluate potential tsunami hazards for the community of Whittier and western Passage Canal area.

The final, highest resolution grid of the western Passage Canal, where the inundation extent was calculated, has a spacing of approximately 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.\n\nResults 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.\nWe modeled inundation extents resulting from 14 different scenarios (tsunami, landslide, and rockfall). Each scenario is described in the text report. This digital data distribution package presents shapefiles that outline the extent of the scenarios that produced a \"significant\" inundation in Whittier. We also include two additional shapefiles that outline where the modeled water depth of the maximum innundation scenario is expected to be 0.5 and 2 meters. The inundation limits and flow depths are results of numerical modeling of tsunami waves with the use of shallow water equations. We conducted all model runs using bathymetric data that correspond to Mean Higher High Water so that the resulting maximum inundation line represents a reasonable worst-case 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 average recurrence intervals for the tectonic source events are poorly known. Scenarios 1 and 2, which are repeats of the magnitude 9.2 great earthquake of 1964, have an estimated median recurrence interval of 589 years, based on paleoseismic data (Carver and Plafker, 2008). The recurrence intervals for tsunamigenic underwater landslides in Passage Canal is unknown. The recurrence interval for the potential rockfall-generated tsunami is also unknown. The data used to calculate the potential extent of tsunami inundation includes: high-resolution topography and bathymetry of Passage Canal, historic records of the 1964 inundation line at Whittier, historic seismicity measurements, pre- and post-1964 bathymetric profiles in the western part of Passage Canal, and related tectonic geometry. The western part of Passage Canal 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. The potential rockfall area require additional in-situ measurements to constrain volume, configuration and dynamics of the potential rockfall failure.\n\n\nThe extent of tsunami inundation in Whittier 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 NGDC NOAA report \"Digital elevation models of Prince William Sound, Alaska-Procedures, Data Sources and Analysis\" by Caldwell, R.J., Eakins, B.W., and Lim, E. According to the corresponding metadata file, the accuracy of the high-resolution DEM developed is determined by the topographic datasets with the vertical accuracy of 10-15 m (33-50 ft). Since the DEM can posses large vertical errors near the shoreline, the topographic datasets are augmented with high-accuracy data, that is, a real time kinematic (RTK) GPS survey within the harbor area and along near-shore areas in Whittier. We estimate that the GPS observations have the vertical accuracy of 1 m (3.3 ft) in flat-lying areas where there are no abrupt topographic changes. Finally, we note that the collected GPS measurements are recorded in WGS84 horizontal datum, with the horizontal accuracy of approximately 3-5 m (10-16 ft). For additional information please reference the \"Grid development and data sources\" section of this report.\n\n\nThe vertical accuracy of the inundation modeling is dependent on the accuracy and resolution of the digital elevation models (DEMs) and tidal datum values that were used to compile the computational grid. We provide additional details about DEM and grid development in the accompanying report. Prior to scenario modeling, bathymetric data were shifted to use Mean Higher High Water (MHHW) as the vertical datum. The depths of inundation shown should be used only as a guideline for emergency planning and response action. Actual inundation water depth will depend on specifics of the earth deformations, on-land construction, and tide level, and they may differ from areas shown by this data. 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 earthquake. These results are not intended for land-use regulation or building-code development.

The topographic datasets were augmented with high-accuracy data, that is, a real time kinematic (RTK) GPS survey within the harbor area and along near-shore areas in Whittier. 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.\nCaldwell, R.J. and others, 2011\n2009\n\n\nModel 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.\nNicolsky, D.J and others, 2011\n2010\n\n\nModel verification - We performed the verification of the numerical model using observations of the 1964 tsunami. We compared results of inundation modeling in Passage Canal and Whittier 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 Passage Canal 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 Whittier and at the head of Passage Canal. See Methodology and data and Modeling results sections of this report for more detail and additional model information.\nSuito, Hisashi and Freymueller, J.T, 2010\nKachadoorian, Reuben, 1965\nJohnson, J.M. and others, 1996\n2010\n\n\nNumerical simulations of hypothetical tsunami scenarios - We assessed hazard related to tectonic and landslide-generated tsunamis in Passage Canal by performing model simulations for each hypothetical earthquake and landslide source scenario. The numerical results for each scenario include extent of inundation, sea level and velocity time series, and tsunami flow depth. See Modeling results section of this report for more detail and additional information.\n2010\n\n\nNumerical simulations of potential rockfall-generated tsunami - We assessed hazard related to two scenarios of the rockfall-generated tsunamis in Passage Canal by performing model simulations. Numerical results for each scenario include extent of inundation, sea level and velocity time series, and tsunami flow depth. See Appendix A section of the associated report for more detail and additional information.\n2010\n\n\nCompilation of maximum inundation zone and maximum flow depths - Compilation of maximum inundation zone and maximum flow depths - We calculated maximum composite extent of 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.\n2010\n\n\nCalculation of the potential inundation lines - For each grid cell in the high-resolution DEM of Whittier, 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. The datum was subsequently changed to the datum of the background image.\n2010\n\n\nData distribution package was edited to add a raster image depicting maximum composite flow depths over dry land. Pixel values provide the modeled depth (in meters) of maximum inundation. For each grid point, the pixel value provides the modeled depth of water (in meters) over previously dry land, representing the maximum depth value of all calculated tsunami scenarios.\n2017\n\n\n\n\nvector\n\n\n\n\n.000001\n.000001\ndecimal degrees\n\n\nWorld Geodetic System of 1984\nWGS 84\n6378137\n298.257223563\n\n\n\n\nMean Higher High Water\n1\nmeter\nAttribute values\n\n\n\n\n\n\nri2011-7-mhhw-shoreline\nThe modern shoreline (mean higher high water - MHHW) of the study area at the time of publication; see Grid Development and Data Sources section of this report to learn more about how this file was created.
