Ralph Haugerud
Ralph Haugerud is a research geologist in the Geology, Minerals, Energy, and Geophysics Center. He is a structural geologist and geologic mapper interested in the evolution of the Pacific Northwest.
Ralph received B.S. and M.S. degrees in Geology from Western Washington University and a Ph.D. in Geological Sciences from the University of Washington. Since joining the USGS in 1986, he has worked in the North Cascades Range, the Salish Lowland, and the Columbia Plateau. From 1990 to 2014 he was technical lead for the Puget Sound Lidar Consortium, and he has been instrumental in developing the GeMS standard for representing geologic maps in a Geographic Information System (GIS). His current efforts focus on the structure of Eocene strata in central Washington, features formed by glacial Lake Missoula outburst floods, and regional map compilation.

Database for the geologic map of the Mount Baker 30-minute by 60-minute quadrangle, Washington (I-2660) Database for the geologic map of the Mount Baker 30-minute by 60-minute quadrangle, Washington (I-2660)
This digital map database has been prepared by R.W. Tabor from the published Geologic map of the Mount Baker 30- by 60-Minute Quadrangle, Washington. Together with the accompanying text files as PDF, it provides information on the geologic structure and stratigraphy of the area covered. The database delineates map units that are identified by general age and lithology following the...

Lifelines and earthquake hazards along the Interstate 5 Urban Corridor: Woodburn, Oregon to Centralia, Washington Lifelines and earthquake hazards along the Interstate 5 Urban Corridor: Woodburn, Oregon to Centralia, Washington
The Interstate 5 highway corridor, stretching from Mexico to Canada, is not only the economic artery of the Pacific Northwest, but is also home to the majority of Oregonians and Washingtonians. Accordingly, most regional utility and transportation systems, such as railroads and electrical transmission lines, have major components in the I-5 corridor. The section of I-5 from Cottage Grove...

The Cottage Lake aeromagnetic lineament: A possible onshore extension of the southern Whidbey Island fault, Washington The Cottage Lake aeromagnetic lineament: A possible onshore extension of the southern Whidbey Island fault, Washington
The northwest-striking southern Whidbey Island fault zone (SWIF) was mapped previously using borehole data and potential-field anomalies on Whidbey Island and marine seismic surveys beneath surrounding waterways. Abrupt subsidence at a coastal marsh on south-central Whidbey Island suggests that the SWIF experienced a MW 6.5 to 7.0 earthquake about 3000 years ago. Southeast of Whidbey...

High-resolution lidar topography of the Puget Lowland, Washington - A bonanza for earth science High-resolution lidar topography of the Puget Lowland, Washington - A bonanza for earth science
More than 10,000 km2 of high-resolution, public-domain topography acquired by the Puget Sound Lidar Consortium is revolutionizing investigations of active faulting, continental glaciation, landslides, and surficial processes in the seismically active Puget Lowland. The Lowland-the population and economic center of the Pacific Northwest-presents special problems for hazards investigations...

Syntectonic remagnetization in the southern Methow block: Resolving large displacements in the southern Canadian Cordillera Syntectonic remagnetization in the southern Methow block: Resolving large displacements in the southern Canadian Cordillera
The Upper Cretaceous Ventura Member of the Goat Wall unit in the southern Methow block of southern British Columbia and northern Washington State holds a syntectonic magnetization. Eight new sites from Manning Park in British Columbia give a mean direction of D = 27.5°, I = 60.1°, k = 304.7, α95 = 3.2° after optimal partial tilt correction. Of five groups of bedded sites from farther...

The December 1872 Washington state earthquake The December 1872 Washington state earthquake
The largest historical earthquake in eastern Washington occurred on 15 December 1872. We used Modified Mercalli intensity (MMI) assignments for 12 twentieth-century earthquakes to determine attenuation relations for different regions in the Pacific Northwest. MMI attenuation for propagation paths east and west of the Cascade Mountains differs significantly only for epicentral distances...
