A 5,000 cubic meter rockfall is seen on cell phone video enveloping a 420 year old Italian church in dust, but the church and its bell tower miraculously escaped serious damage. The Santuario di Gallivaggio (Sanctuary of Gallivaggio), close to the Swiss border, and the surrounding town had been evacuated for several days and there were no reports of injuries.
The Colorado Geologic Survey has a very comprehensive overview of the geologic hazard of rockfall in all its many forms in their latest issue of RockTalk newsletter. The entire 24-page newsletter is devoted to various aspects of the problem, mitigation options and case studies all with excellent photos. I highly recommend that you check it out.
