Thanks to Greg Stock for bringing this one to my attention. Yosemite National Park have produced a video providing information for visitors about the hazards associated with rockfalls. It includes an extraordinary piece of footage - captured by a visitor to the park - of a rockfall detaching from the cliff, fragmenting on impact on the the slope, and then travelling down the talus slope. The video of the detachment event is fantastic - I have never seen anything as good. However, the rest of the video is great as well, and will be very valuable to those trying to provide improved awareness rockfalls in many environments. The video should be viewable below (click on read more to see the rest of the post):

ReplyDeleteGreat video - thanks for the link!
ReplyDeleteThanks for the link. It was quite interesting and then I even watched other segments about Yosemite park which were excellent.
ReplyDeleteIt is really nice to find a science blog that is not political too as in global warming caused this. I shall return and learn.
