We’re pleased to announce the release of two digital datasets that are now available for download.

Landslides and Landforms (Digital Data Series 12), version 4.1

This update includes landslides mapped during the past several years, including landslides mapped at 1:100,000-scale from the recently published Tacoma quadrangle, as well as numerous 1:24,000-scale landslides from recent mapping by Joe Dragovich and Michael Polenz.

Shear Wave Database (Digital Data Series 17), version 1.0

This new dataset contains shear wave data within the upper 30 meters of the crust from strong motion stations in Washington. The data was compiled from several shallow-seismic site characterizations prepared from the U.S. Geological Survey, and from a 2008 shear wave database by Bilderback and others.
