The summer of 2015 brought an “exceptionally large” number of rockslides in the Swiss Alps because of warmer temperatures, according to a report from the Institute for Snow and Avalanche Research.

The Davos-based organisation found that most of those rockslides occurred in areas higher than 2,500 metres above sea level. They were caused by above-average air temperatures, with the freezing altitude located above 4,000 metres for a period of about six weeks.

The largest such rockslide occurred on September 2 in the Valais region, where 80,000 cubic metres of rock were dislodged. According to the institute, a volume of 5,000 cubic metres is about equal to five houses.

The video below shows an example of a significant rockslide event in Switzerland in October.
