According to the Landslide Blog, this rockfall video was taken in Maoxian County in Sichuan Province of China on or around July 17, 2014. It shows a very dangerous rockfall event with people running from their cars. In one scene you can even see someone being struck by a rock and knocked over. The person is later able to walk away with assistance. Towards the end of the video, even the windshield of the videographer is struck by a smaller rock and cracked. Very dramatic and very scary video!
