Online_Linkage: http://dx.doi.org/10.14509/26671 Description: Abstract: The purpose of this study is to evaluate potential tsunami hazards for the community of Sitka. We numerically modeled the extent of inundation from tsunami waves generated by near- and far-field tectonic sources. We performed numerical modeling of historic events at Sitka, such as the tsunami triggered by the 1964 Great Alaska Earthquake, and the tsunami waves generated by the recent 2011 Tohoku and 2012 Haida Gwaii earthquakes. Hypothetical tsunami scenarios include variations of the extended 1964 rupture, megathrust earthquakes in the Alaska Peninsula region and in the Cascadia subduction zone, and a thrust earthquake in the region of the Queen Charlotte-Fairweather fault zone. Results of numerical modeling combined with historical observations in the region are intended to provide guidance to local emergency management in tsunami hazard assessment, evacuation planning, and public education for the reduction of future tsunami risk. Purpose: Large seismic events occurring in the vicinity of the Alaska Peninsula, Aleutian Islands, and Gulf of Alaska have a very high potential for generating both local and Pacific-wide tsunamis. Saving lives and property depends on how well a community is prepared, which makes it essential to estimate the potential flooding of the coastal zone in the case of a local or distant tsunami. The Alaska Tsunami Mapping Team (ATMT) participates in the National Tsunami Hazard Mitigation Program (NTHMP) by evaluating and mapping potential inundation of selected parts of the Alaska coastline using numerical modeling of tsunami wave dynamics. The communities are selected for inundation modeling in coordination with the Division of Homeland Security and Emergency Management (DHSEM) with consideration for location, infrastructure, availability and quality of bathymetric and topographic data, and community involvement. The Sitka tsunami inundation maps described in the associated manuscript represent the results of the continuous effort of state and federal agencies to produce inundation maps for many Alaska coastal communities.

We have considered several tsunami scenarios and have provided an estimate of maximum credible tsunami inundation. Actual conditions during a tsunami event may vary from those considered, so the accuracy cannot be guaranteed. Landslide tsunami sources are not included in the current study due to unknown potential impact of such events on Sitka. The limits of inundation shown should only be used as a guideline for emergency planning and response action. Actual areas inundated will depend on specifi cs of earth deformations, on-land construction, and tide level, and may differ from areas shown on the map. The information on this map 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. 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 calculated tsunami inundation limits for tectonic source scenarios. However, tsunamis caused by underwater slope failures are also a significant hazard in the fjords of coastal Alaska and other high-latitude fjord coastlines. Southeast Alaska has a long record of tsunami waves generated by submarine and subaerial landslides, avalanches, and rock falls. While we acknowledge that communities in southeastern Alaska are considered at risk from locally generated waves because of their proximity to landslide-prone fjords in a seismically active zone, we did not quantify this category of landslide tsunami hazard for Sitka in the current report due to poor constraints on the parameters of potential slides, such as locations, volumes, and geotechnical properties. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The extent of tsunami inundation was calculated through numerical modeling of water waves over bathymetry and topography. To efficiently compute a detailed map of potential tsunami inundation, we employed a series of nested computational grids. A nested grid allows for higher resolution in areas where it is needed, without expending computer resources in areas where it is not. The computational grid was based on digital elevation models (DEMs) obtained from various U.S. federal and academic agencies. The highest level of horizontal resolution of the grid used for inundation modeling is about 15 m (49 ft). This scale is mostly limited by the computational resources necessary to compute the tsunami inundation at the higher resolution. The 15 m (49 ft) resolution is high enough to describe major relief features, but small topographic features, buildings, and other facilities cannot be accurately resolved by the existing model. For additional information please reference the Grid Development and Data Sources section of the associated manuscript. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The 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. 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.

These grids of increasing resolution allowed us to propagate waves generated by both distant and local sources to Sitka. 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. The bathymetric and topographic relief in each nested grid is based on digital elevation models (DEMs) developed at the National Geophysical Data Center (NGDC) of the National Oceanic & Atmospheric Administration (NOAA), in Boulder, Colorado. The extent of each grid used for Sitka mapping is listed in table 1 of the manuscript. See Methodology and data section of the associated manuscript for more detail and additional data source information. Source_Used_Citation_Abbreviation: Hickman, P.J. and others, 2012 Source_Used_Citation_Abbreviation: Lim, E. and others, 2011 Process_Date: 2011 Process_Step: Process_Description: Model validation - The numerical model that we 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 the associated manuscript for more detail and additional model information. Source_Used_Citation_Abbreviation: Nicolsky, D.J and others, 2011 Process_Date: 2011 Process_Step: Process_Description: Model verification - We examined the tsunami effects at Sitka from the most significant earthquakes of the last century. For model verification, we chose the 1964 Alaska tsunami because it generated the highest recorded wave at Sitka, while the Tohoku 2011 and the Haida Gwaii 2012 events represent the far- and near-field tsunami sources, respectively, with different directional properties. We verified the numerical model by comparing results of the inundation modeling with observations collected shortly after the event. First, we simulated the tectonic tsunami in Sitka using an output of a coseismic deformation model of each of the earthquakes as an initial condition for water waves. Then we compared the modeled inundation zones with the observed extent of inundation. See Methodology and data and Modeling results sections of the associated manuscript for more detail and additional model information. Source_Used_Citation_Abbreviation: NOAA/NWS, 2012 Source_Used_Citation_Abbreviation: NOAA/WDS, 2012 Process_Date: 2012 Process_Step: Process_Description: Numerical simulations of hypothetical tsunami scenarios - We assessed hazard related to tectonic tsunamis in Sitka by performing model simulations for each hypothetical earthquake source scenario. Numerical results for each scenario include extent of inundation, sea level and velocity time series, and tsunami flow depth. See Modeling results section of the associated manuscript for more detail and additional information. Process_Date: 2012 Process_Step: Process_Description: 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. Process_Date: 2012 Process_Step: Process_Description: Calculation of the potential inundation lines - For each grid cell in the high-resolution DEM of Sitka, we determined whether the cell was inundated by waves or stayed dry throughout the entire simulation. Then, we defined a function such that it is equal to one at the center of each wet cell and is 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 resultant contour line (or a collection of lines if the contour is not a simply connected) was directly exported to the ArcGIS using WGS84 datum.
