Breaching of moraines can be triggered by avalanches, earthquakes or a natural collapse of moraines due to excessive pressure from water. It will be difficult for guided companies to ensure people will be able to climb safely, Richards said. Schaefer hypothesized that some kind of mechanism triggered a landslide and that the resulting water pressure eventually burst the dam, causing the mass to plunge down the "extremely steep" flank. The flood entirely damaged the channel constriction with several pillars. Landslides, avalanches, earthquakes, and volcanic eruptions often trigger GLOFs.
