Utah Releases Landslide Susceptibility Map

[Updated May 30, 2008] I forgot to publish this post to the front page, whoops! The two links still have excellent information. In particular, Dave’s Landslide Blog has coverage of the many landslide lakes and the efforts to breach some of them. [/Update]

For more coverage on landslides related to the earthquake, I recommend Dave’s Landslide Blog. Geology.com also has very comprehensive coverage as well. (AFP Photo)
