Online map shows Oregonians whether their home may slide away

OR DEPT. OF GEOLOGY NEWS RELEASE-- The Oregon Department of Geology and Mineral Industries (DOGAMI) has released an updated online interactive map viewer for the second release of the Statewide Landslide Information Database (SLIDO-2).

SLIDO-2 web viewer:

Landslides are one of the most common and damaging geologic hazards in Oregon. Average annual damage from landslides in Oregon exceeds $10 million, and in those years of severe winter storms losses can exceed $100 million. As population growth continues and development into landslide susceptible terrain occurs, damage and loss from this natural hazard will continue to increase.

"Landslides, especially during rainy seasons, should be no surprise to Oregonians," said State Geologist Vicki McConnell. "SLIDO-2 is a continuation of our comprehensive and systematic approach to cataloging the nature and scope of the hazard. This information helps us to work with communities to minimize landslide risks."

The online map lets viewers zoom to their own addresses to see what landslides have been mapped in the area. Clicking on a landslide on the map displays additional information about the landslide. Be aware that any maps generated from the web tool are for general information only and should not be used for planning purposes.

SLIDO-2 was partially funded by the Oregon Geospatial Enterprise Office. SLIDO-1 was partially funded by the U.S. Geologic Survey Landslide Hazards Program.
