King County Leads the Way on Landslide Mapping Efforts

King County has recently come out with an interactive landslide map (kingcounty.gov/iMapLandslide/). The project is an impressive effort and may be a good model on how to put together landslide mapping. The iMap is interactive and will be a great resource as further planning and risk assessment is undertaken.

One intriguing example:



The LiDAR imagery shows a huge low-angle liquefaction spread slide in the Tolt River valley. Dragovitch and others (2012) suggest the slide may have been seismically induced and possibly associated with the Carnation Fault.
