Interesting landslide footage from La Jolla, California

The La Jolla landslide in San Diego California occurred in October 2007, destroying three houses and a road, and leaving many more damaged. The landslide is currently the subject of a lawsuit that was filed by the householders. I am not going to comment further on the slide whilst this is going on, but as part of the evidence in the case some mobile phone footage has emerged of the slide as it occurred. This footage is unusual in that it covers a progressive, non-catastrophic slide, essentially showing the tension cracks opening as the slide occurred. The footage can be viewed here. The complete (8 minute) footage, available on that page, is worth viewing.
