On June 11, a huge chunk of the summit of Fluchthorn (also known as Piz Fenga) collapsed. The 3,399m mountain lies in the Silvretta Alps on the border between Austria and Switzerland. Thousands of tons of rock fell because of thawing permafrost.
Miraculously, local authorities report no injuries. Onlookers recorded the collapse.
This is not the first collapse in the area. Last month, authorities evacuated residents of the Swiss village of Brienz because of rockfall danger.
