Wong Angie J. Venturato Eric L. Geist 2006 vector digital data Data Series 236 Menlo Park, California U.S. Geological Survey http://pubs.usgs.gov/ds/2006/236/ This data set is a polyline shapefile representing the tsunami inundation line for the Alaska 1964 event based on observations and associated information obtained by Tom Horning (1997). The polyline was digitized from a line drawn by Tom Horning on an orthophoto taken in 1997. This data set is one of a collection of spatially referenced digital files in a geographic information system related to the Seaside, Oregon, Tsunami Pilot Study. Federal Emergency Management Agency (FEMA) Federal Insurance Rate Map (FIRM) guidelines do not currently exist for conducting and incorporating tsunami hazard assessments that reflect the substantial advances in tsunami research achieved in the last two decades (Tsunami Pilot Study Working Group, 2006). Therefore, as part of the FEMA Modernization Program, a Tsunami Pilot Study was carried out in the Seaside/Gearhart, Oregon, area to provide information from which tsunami mapping guidelines could be developed. This area was chosen because it is typical of coastal communities in the section of the Pacific Coast from Cape Mendocino to the Strait of Juan de Fuca. There was also considerable interest shown by state agencies and local stakeholders in mapping the tsunami threat to this region. The study was an interagency effort by scientists from the U.S. Geological Survey, the National Oceanic and Atmospheric Administration, the University of Southern California, and the Middle East Technical University. We present the GIS data from that report in this publication. These data are intended for science researchers, students, policy makers, and the general public. The data can be used with geographic information systems (GIS) software to display geologic and oceanographic information. 2006 publication date Complete None planned -123.939037 -123.910039 46.036122 45.975797 USGS Metadata Identifier USGS:ea08a696-536d-46fc-b52b-275b961bba05 None National Oceanic and Atmospheric Administration NOAA Center for Tsunami Research U.S. Geological Survey USGS Coastal and Marine Geology Program CMGP Western Coastal and Marine Geology WCMG polyline shapefile tsunami inundation observations ISO 19115 Topic Category oceans environment geoscientificInformation USGS Thesaurus tsunamis geospatial datasets Geographic Names Information System Seaside Oregon USA United States North America none 1997 None.
