Impressive roadside landslide in Pomona, California

Thanks to reader CConkle for the heads-up on this one. An impressive slide happened this morning by the side of Freeway 10 near to Pamona in California. The slide has completely blocked the road (pictures from the LA Times):




It is uite interesting that the weather does not indicate an obvious trigger for what appears to be a failure on a reprofiled slope. However, California has suffered recent exceptional rainfall in the last few weeks, so it may be progressive failure is the key factor here.

Most recent reports suggest that the slope is still moving and the road is likely to be closed for a week.
