Catalog of source data for tsunami inundation modeling in Alaska

Description

Catalog of source data for tsunami inundation modeling in Alaska, Digital Data Series 21, provides tsunami source models developed for tsunami hazard assessments of at-risk coastal communities throughout Alaska. Tsunami sources include great (M8 or more) earthquakes in Alaska and around the Pacific Ocean Basin, as well as submarine and subaerial landslides, and include slip distributions and seafloor deformations and landslide volumes, respectively, as georeferenced TIFF files. Alaska Division of Geological & Geophysical Surveys and the University of Alaska, Alaska Earthquake Center staff initiated the tsunami hazard assessment program in the late 1990s as a component of the NOAA/NWS-funded National Tsunami Hazard Mitigation Program (NTHMP). This resource and supporting data repository provide a comprehensive, public-facing, searchable catalog of all tsunami sources used in decades of Alaska tsunami hazard studies to promote transparency, facilitate scientific reproducibility, and satisfy NTHMP archival requirements. Seismic and non-seismic digital tsunami sources from future hazard studies will be appended to this database as appropriate. The files are and indexed by the community names and the publications in which they are utilized. Please see the linked accompanying reports for a more detailed description of the development and use of individual tsunami source models. This data collection is released with an open end-user license. All files can be downloaded from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/30953).
