San Bernadino National Forest landslide video
One of a number of new landslide videos that have been published in the last few days comes from San Bernadino National Forest in Southern California, triggered by the latest in a procession of intense rainfall events in recent weeks. This is a very impressive video of a large landslide in the Forest Falls area. In many ways the most interesting aspect is the high energy mobilisation of the flow in the valley below the landslide, which was just caught by the person making the film:-
Another, I think earlier, movement event of this landslide in San Bernardino National Forest was captured from a helicopter by Fox11. They report that this area is known as Slide Canyon:-
A still from this video captures rather well the extent of the landslide, which presumably mobilised in the later event:-

A landslide under the Pfeiffer Canyon Bridge in the Big Sur, California
Meanwhile, back in the USA this news report shows the effects of a landslide beneath the Pfeiffer Canyon Bridge in the Big Sur, California.
The damage to the bridge is spectacular:
It is hard to imagine that a structure with such serious damage can be saved, but Caltrans is undertaking inspections to determine the way forward. More rain is forecast.
