Publications and Maps
   

Since its creation in 1890, the Washington Geological Survey has released over 1,000 publications and maps. Publications contains everything that we produce, from reports to maps. Maps contains a collection of all of our map-based publications only.

We announce the release of publications and other news through our blog, Washington State Geology News. If you'd like to receive notification when we publish something new, you can subscribe by email on the blog, or directly here. In-print maps can be purchased from the Washington Department of Enterprise Services myFULFILLMENT online store

WGS Publication Catalog

The publication catalog lets you find anything that we have ever made since 1890. The catalog also provides a map that shows where each publication is located and a preview of the PDF.

Publications List

Our downloadable Publications List contains all of our publications with links to their PDFs. It also shows which publications are "in print" or have paper copies for sale. The publications are listed in chronological order within each series. If you don't know the series and number, you can search the publications list using Ctrl+F (Find).

Washington Geology Library

The Washington Geology Library Online Catalog is a collection of all publications, regardless of publisher, having to do with Washington geology. There are over 80,000 items in the library and more are added every year.

Geologic Hazard Maps

  • Tsunami evacuation
  • Tsunami inundation
  • Shallow landslide hazard forecast
  • Active faults and earthquakes
  • Seismic scenarios
  • NEHRP site class and liquefaction susceptibility
  • Seismic design categories
  • Hazardous minerals
  • Lahar hazards
  • Landslides
  • Inactive and abandoned mines

  • Tsunami evacuation routes were developed to assist coastal residents and visitors find safer locations in case of an earthquake and tsunami. The published brochures are for specific areas.

    The Geologic Information Portal has a Tsunami Evacuation single-topic map that allows you to search for addresses and locations of interest. The information on the portal and in the brochures is the same.
    Evacuation Brochures

    This map shows all completed tsunami evacuation brochures for Washington. Clicking on a region will download the brochure. Use your scroll wheel or the zoom buttons in the upper left corner to zoom.

  • Inundation maps show areas at risk of inundation by tsunamis that are generated from large earthquakes. These maps are based on model results from hypothetical earthquake scenarios on the Cascadia subduction zone, Seattle fault, or Tacoma fault.
    Reports and Maps

    This map shows all completed tsunami inundation maps for Washington. Clicking on a region will download the publication. Use your scroll wheel or the zoom buttons in the upper left corner to zoom.

  • In cooperation with NOAA, we have developed a model based on recent and predicted rainfall data that may forecast hazards and may reduce losses from landslides. Clicking the icon to the right will take you to the forecast map page.

  • Geologists from the Washington Geological Survey map and characterize faults throughout the state every year. We also combine and publish these data for the entire state.

    The Geologic Information Portal has a Natural Hazards single-topic map that shows active faults and earthquakes. Click the "Earthquake Data" button in the Map Contents window to display faults and earthquakes.
    Reports and Maps

    Click below to download the 2014 state-wide compilation of active faults and earthquakes.

  • The Washington State Seismic Scenario Catalog contains loss estimates for a suite of earthquake scenarios. These scenarios were selected to represent reasonable estimates of the most serious earthquake hazards everywhere in Washington as a basis for planning.

    The Geologic Information Portal hosts the Seismic Scenario Catalog. Choose a scenario to see the modeled damage to infrastructure.

  • In response to the Nisqually earthquake of 2001, the Survey was awarded a grant by FEMA and the Washington Emergency Management Division to develop two types of earthquake hazard maps for every county in the state—liquefaction susceptibility maps, which outline areas where water-saturated sandy soil loses strength during earthquake shaking, and NEHRP (National Earthquake Hazards Reduction Program) site class maps, which outline areas where soils amplify ground shaking. The maps will be used by state and local governments to update existing hazard mitigation plans and to delineate geologically hazardous areas under the Growth Management Act.

    The Geologic Information Portal has a Natural Hazards single-topic map that contains the site class, liquefaction, and seismic design categories data. Click the "Ground Response" button in the Map Contents window.
    Reports and Maps

    This map shows all site class and liquefaction susceptibility maps for Washington, by county. Clicking on a county will display links to the published maps and reports.

  • Seismic Design Category Maps for Residential Construction were developed and published in 2007 as two PDFs. Click below to download a .zip file with both maps.

    The Geologic Information Portal has a Natural Hazards single-topic map that contains the site class, liquefaction, and seismic design categories data. Click the "Ground Response" button in the Map Contents window.

  • The Survey maintains a database of hazardous mineral locations from mines or prospects known to have produced uranium, mercury, asbestos, or arsenic. The database also contains the locations of mapped ultra-mafic rocks that may potentially contain asbestos and a radon hazard map.

    The Geologic Information Portal has data that shows known hazardous mineral locations and radon hazards. Click the "Minerals" button in the Map Contents window.

  • The Survey works with the U.S. Geological Survey and the Washington Emergency Management Division to study and develop response plans for lahars. Geologists with the Survey have studied lahars as a part of ongoing efforts to map the geology of Washington state. These publications can be searched on the Washington Geology Library catalog.

    The Geologic Information Portal has a Natural Hazards single-topic map that contains lahar hazards and land parcels at risk from potential lahar scenarios. Click the "Volcanoes" button in the Map Contents window.
    Reports and Maps

    The following maps show generalized lahar hazards for each of the major volcanoes in Washington. Each map is associated with a report. Check out the Geologic Information Portal (below the table) for detailed hazards near Mount Rainier.

    Mount Baker Potential Volcanic Hazards from Future Activity at Mount Baker
    Glacier Peak Volcanic-Hazard Zonation for Glacier Peak

  • The Geologic Information Portal has a geologic map theme that shows mapped landslides in the state. These landslides are compiled from existing geologic maps. The absence of a mapped landslide does not indicate the absence of landslide hazard. Click the "Landslides" button in the Map Contents window.

  • Many of Washington's metal mines are now abandoned, and the Survey has steadily made headway in inventorying the history, physical characteristics, and geologic and environmental hazards of over 60 abandoned mine sites or districts. Only the mines with more than 2,000 feet of underground development, more than 10,000 tons of production, or had a known mill site or smelter have been evaluated at this point.

Resource Maps

  • Aggregate resources
  • Oil and gas resources
  • Geothermal resources

  • Currently, there is no oil and gas production in Washington. About 600 exploratory gas and oil wells have been drilled in Washington, but large-scale commercial production has never occurred. Small amounts of gas (1.3 billion cubic feet of gas) were produced briefly from the Rattlesnake Hills Gas Field, north of Richland. A small amount (12,000 barrels) of oil was produced in the Ocean City area from 1957-1961.
