Experts at the United States Geological Survey (USGS) have produced a series of new landslide maps of Seattle that will provide property owners, government agencies and utilities with improved landslide information. The new maps include a Shallow Landslide Hazard Map; Landslide Terrain Map using LIDAR Imagery; Map of Landslide Probability and Recurrence; Prototype Maps Linked to Rainfall; Rainfall Thresholds for Landslides and Early Warning; and Deep Landslide Hazards Map.
"We are very pleased to have these new resources," said City of Seattle Emergency Management Director, Barb Graff. "An improved understanding of landslide hazards in Seattle can help government and private property owners reduce the threat to both people and property."
The new maps are the product of a multi-year study by the USGS following the devastating landslides in the region in 1996/97 and are part of the larger Seattle Project Impact, a public-private partnership, to improve safety in the region against such natural hazards as landslides and earthquakes.
Since 1997, the City of Seattle has
City of Seattle staff have begun a review of the maps to determine how this information can assist regulators and property owners in protecting against landslide hazards and damage. The maps generally reinforce and confirm information provided in Environmentally Critical Areas maps currently used by the City of Seattle.
Several USGS maps and reports related to landslide hazards in Seattle are available online at http://landslides.usgs.gov/learningeducation/publications.php. The new maps identifying shallow and deep landslide hazards will be available soon.
