How the shift of warm ice in #polythermal #glacier triggers #Bergsturz -sized rock slides: i.e. Bliggspitze (AT), Piz #Scerscen (CH) -> Keyword: buildup of hydrostatic pressure; new failure mechanism proposed esurf.copernicus.org/articles/13/...
Two absolutely iconic images of the 5.6 km long Piz #Scerscen rock avalanche deposit! 🗻❄️🪨
Striking to note that it reached almost the LIA frontal position (located few tens of meters downstream)
