What is the Statewide Landslide Information Database for Oregon?

SLIDO release 3.0 is compilation of landslides in Oregon that have been identified on published maps. The database contains only landslides that have been located on these maps. Many landslides have not yet been located or are not on these maps and therefore are not in this database. This database does not contain information about relative hazards. The interactive map lets you view information on location, type, and other attributes related to 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SLIDO-3.0 includes 37,226 landslide deposit polygons and landslide-related features from 347 published and unpublished studies, 12,075 historical landslide point locations, and 72 locations of detailed studies on individual landslides. The original studies vary widely in scale, scope, and focus, which is reflected in a wide range in the accuracy, detail, and completeness with which the landslides are mapped.
