What does this data set describe?

Title:
Maximum Velocity Zones at Seaside, Oregon based on Near-field Sources
Abstract:
This data set consists of ASCII raster grids representing tsunami maximum V zones of the Seaside-Gearhart, Oregon region based on Models 15-26 as defined in Tsunami Pilot Working Study Group (2006). Models 15-26 results are based on near-field tsunamigenic earthquakes along the Cascadia subduction zones. Maximum V zones are calculated by (u^2+v^2)/(gh) where u is velocity in the x-direction, v is velocity in the y-direction, g is gravity, and h is depth.

  6. How does the data set represent geographic features?

    1. How are geographic features stored in the data set?

      This is a Raster data set. It contains the following raster data types:

      • Dimensions 180 x 126 x 1, type Grid Cell

    2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000556. Longitudes are given to the nearest 0.000556. Latitude and longitude values are specified in Decimal degrees.

      The horizontal datum used is North American Datum of 1983.
      The ellipsoid used is Geodetic Reference System 80.
      The semi-major axis of the ellipsoid used is 6378137.000000.

Why was the data set created?

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.
