SALEM, Ore. (KOIN 6) — More than 46,000 known landslide locations are now included in a statewide database designed to increase Oregon’s understanding of where future landslides may occur.
The Oregon Department of Geology and Mineral Industries (DOGAMI) released on Wednesday a version 3.0 of the Statewide Landslide Information Database for Oregon (SLIDO), which compiles all landslides that have been identified on published maps.
“We’ve mapped more landslides in the last five years than we did in the previous 60 years,” said Bill Burns, DOGAMI engineering geologist in a written statement. “Land that has slid tends to slide again, so mapping landslide locations is critical.”
Lidar, a new tool that provides accurate high-resolution images of the earth’s surface, enabled geologist to expanded Oregon’s landslide knowledge. Almost all of the nearly 20,000 landslides mapped since 2009 have come from geologic and landslide mapping that used lidar, according to DOGAMI.
The SLIDO interactive map can be viewed at www.oregongeology.org. DOGAMI said finding landslide locations on the map is as easy as entering an address.
