Oregon geologists expand statewide landslide database, launch interactive map

SHARE

US: More than 46,000 known landslide locations have been included in the latest statewide database launched by Oregon Department of Geology and Mineral Industries (DOGAMI). For Version 3.0 of the Statewide Landslide Information Database for Oregon (SLIDO-3.0), geologists have used LiDAR technology to map almost all of the landslides that have occurred since 2009.

SLIDO release 3.0 is compilation of landslides in Oregon that have been identified on published maps.

Above: SLIDO release 3.0 is compilation of landslides in Oregon that have been identified on published maps.

This GIS compilation of landslide areas was derived primarily from published geologic reports and geologic hazard studies by the U.S. Geologic Survey (USGS), the Oregon Department of Geology and Mineral Industries (DOGAMI), and in lesser amounts thesis studies and regional studies by the U.S. Forest Service (USFS) in the state. The data, which has been compiled and plotted on a digital map, is available as a free download, as web services, or for purchase on DVD. The interactive map lets users view information according to location, type, and other attributes related to the identified landslides in Oregon.

SLIDO-3.0 includes 37,226 landslide deposit polygons and landslide-related features from 347 published and unpublished studies, 12,075 historical landslide point locations, and 72 locations of detailed studies on individual landslides.
