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. The compilation of co-seismic slip distributions for hypothetical earthquakes, along with corresponding maps depicting regional uplift/subsidence, serves as input for numerical models addressing tsunami generation, propagation, and inundation in specific target communities. Certain communities face potential threats from tsunamigenic landslides, where the initial thickness of these hypothetical landslides is also considered. Several awards from the National Oceanic and Atmospheric Administration/National Weather Service Office (NOAA/NWS) through the National Tsunami Hazard Mitigation Program to the Alaska Division of Homeland Security and Emergency Management, the University of Alaska, Fairbanks, and the Alaska Division of Geological and Geophysical Surveys, funded the generation of these data. This acknowledgment does not imply an endorsement by NOAA/NWS. Numerical calculations for this work were supported by High-Performance Computing resources at the Research Computing Systems unit at the Geophysical Institute, University of Alaska, Fairbanks. Multiple authors contributed to the development of the tsunami sources over the lifespan of the project; detailed information is provided in the originating tsunami modeling reports.

Vertical Positional Accuracy Report Throughout the project, we use WGS84 geoid to specify coordinates of the co-seismic slip and ground surface deformation. The initial landslide thickness is related to the current digital elevation model (DEM) used for modeling tsunami propagation and runup; detailed information about the DEM is provided in the associated tsunami modeling report. DGGS anticipates ongoing development of additional seismic and non-seismic digital tsunami sources from future hazard studies will be appended to this database. DGGS anticipates ongoing development of additional seismic and non-seismic digital tsunami sources from future hazard studies will be appended to this database. The results we generate with numerical models are dependent on the resolution of input datasets (i.e. fault geometries) and topographic and bathymetric data used in computations. Therefore, the known and unknown uncertainty parameters related to each model will be unique. This lineage was generated by the FGDC CSDGM to 19139 transformation Earthquake sources - We generate geologically plausible hypothetical co-seismic slip distributions that produce maximum-considered (i.e., worst-case) tsunami inundation in target communities. We constrain these earthquake scenarios based on the current, collective body of knowledge about subduction zone geometry and dynamics using geodetic, geologic, and paleoseismic data in the appropriate regional setting. We also utilize a broader understanding of subduction zone behavior from the global scientific community. The considered co-seismic slip distribution is prescribed on the subducting plate interface or along the hypothetical crustal faults in the area, see details in the corresponding modeling report for details of the interface geometry. Numerical calculations of the co-seismic deformation are conducted with the MATLAB or FORTRAN software package using the Okada solution, derived from a Green's function solution to the elastic half-space problem. 2024-01-01T00:00:00 Landslide sources - We generate landslide tsunami sources based on historical data or by identifying signatures of submarine slides in modern bathymetric data near our target communities. The initial landslide volume and thickness profiles are computed in MATLAB. 2024-01-01T00:00:00 otherRestrictions Metadata Use Constraints: If the user has modified this metadata file in any way, the user is obligated to describe the types of modifications the user has made.
