Open Thread

Atrios quipped today about CNN paying attention to the buckling roads in San Diego. One of the questions people are asking about that landslide is "who's at fault?" Good question. It turns out the San Diego paper has an excellent answer (watch the video with retired geologist, Pat Abbott). The slide that caused the collapse of the road and the houses on the hillside was due to a real fault: the Rose Canyon fault. The upward movement of the fault caused the loosely consolidated mud-sediments which had been raised from the ocean floor to sit on an ever increasing incline and gravity is taking its toll. If there is a human blame, it is building houses on this type of hillside, because nature is doing exactly what would be expected.

It's your thread now.
