Landslide Blocks Road in LA, Inconveniences UCLA Hoops Fans
Mud and debris from a small landslide closed a portion of Sepulveda Blvrd. In Westwood California on Thursday. The slide took out at least one local resident’s backyard and was large enough to block several lanes of the roadway with debris up to 6-ft high in addition to knocking out several power poles and disrupting service. The material was cleared up by 10pm but not before it cause some inconvenience to UCLA basketball fans on their way to watch their team beat Stanford. The LA Times reports that there were questions about possible broken water lines, of course it is the old "chicken or the egg" argument that’s been seen before (including on a recent landslide) about whether the broken water lines contributed to the landslide, or the landslide caused the water line breaks.

Sea to Sky Highway Landslide
Earlier this month, there was a massive slope failure on the "Sea to Sky" highway in British Columbia. It is interesting to note that this same area had a large rockslide in 1965, and a photo of this failure is featured on the cover of the classic text, Rock Slope Engineering by Hoek and Bray. The media played up the aspect that this highway is one of the only ways to access the site of the 2010 Winter Olympic games hosted by Vancouver.
The composite image above shows the book cover and the recent rockslide event (Photo credit: Erik Eberhardt of the University of British Columbia by way of Dave’s Landslide Blog). Dave has done a fabulous job collecting photos, facts and links from around the web. In a follow up post, he added some additional photos and discussion. I recently came across an article that described how the highway originally was slated to have a tunnel bypassing the slide, but that the price tag of $200 million (CAN?) for a 1-km stretch killed the project.
