A mountainside rockslide sent rocks and dust cascading into the air above popular Oeschinensee in Switzerland. Footage filmed on August 8 shows part of the mountainside collapsing as visitors watched from across the lake. Tourist Eva Ramió Planellas was preparing to swim when she heard a loud rumbling and began filming the rockslide. Authorities in Bern said they were aware of the footage but had received no reports of injuries or damage.
