A teenage girl strolling on the beach in Pacifica, California was buried alive by a landslide. She was buried up to her chest, and a passer-by dug her out with his bare hands while more soil and rock fell around them. Story at KTVU San Francisco. See a nice oblique aerial photo of the beach prior to the landslide here. Those slopes don’t look particularly stable to me but what do I know?
Back in March of 2008 there was a landslide that closed SR 87 in between Phoenix, Arizona and Payson. It’s been of great interest to me since it is in my state and affected a highway. I was hoping my firm (NCS Consultants, LLC) might be asked to work on the remediation through our on-call contract but it didn’t happen. Its probably for the best, it sounds like it’s been a troublesome geotechnical engineering problem. Fast forward to last week, and the slide area was in the news again because the slope is still moving and apparently causing some additional deformation of the roadway. (Photo by ADOT)
I had heard about this a while ago through our ADOT contacts, but I make it a policy not to take advantage of my contacts through my day job for GeoPrac.net content (not without permission anyway). So I didn’t want to blog about it until it hit the mainstream media. Last week, the Arizona State Geologist blogged about the SR 87 slide moving again, as did Ken through his AEG Arizona Section blog. It was even covered on one of my favorite blogs, Dave’s Landslide Blog. I finally have a chance to wade through these blog posts and some of the reports and videos to present a summary of the situation, available information and offer my own perspective.

Nearly 100 villagers living upstream from the Three Gorges dam have been forced to leave their homes under threat of a landslide, which officials fear was disturbed during the filling of the dam’s reservoir last year, Xinhua News Agency reported last week. Read on for more info. (Photo by enkai)
