Wong Angie J. Venturato Eric L. Geist 2006 vector digital data U.S. Geological Survey Data Series 236 Menlo Park, California U.S. Geological Survey http://pubs.usgs.gov/ds/2006/236/ Water level probability distributions were calculated to understand the background tides and sea level variations of the Seaside, Oregon coastal region. Tabular data include observed and predicted water level heights and probability distributions for specified sites in the Pacific Northwest region from 1983-2001. 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 and associated tabular data from that report in this publication. These data are intended for science researchers, students, policy makers, and the general public. 1983 2001 ground condition Complete None planned -125.0 -123.0 47.0 44.0 none water level tide probability density function probability exceedance cumulative density function Geographic Names Information System Seaside, Oregon South Beach, Oregon Astoria, Oregon Toke Point, Washington Oregon Washington USA none 1983 2001 None.
