At an elevation of 2800 metres, the lower end of a glacier snapped off. The break-off had a width of about 80 metres and a height of 25 metres. The detached volume was estimated to be 65,000 ± 10,000 cubic metres. [6] The seismic energy released was comparable to an earthquake of 0.6 M. [1]
Looking into the crater, the camera captured hourly photographs of volcanic dome growth during the 2004-2008 eruption. The station also captured the advance of the west arm of Crater Glacier as it moved northeast around the 1980-1986 and 2004-2008 lava domes, joined with the east arm of the glacier, and pushed northward onto the crater floor.
The William Glacier in Antarctica partially collapsed in the same week as Antarctica's hottest recorded day at 65ºF. It lasted for several minutes and stretched half a mile.

The Trift glacier forefield lies in the retreat area of the Trift Glacier in the municipality of Innertkirchen, Canton Bern, between the Susten Pass and the Grimsel Pass. It extends from the glacier break-off (approx. 2300 m above sea level) to the Sunnige Trift (1325 m a. sea level) below the Graaggilamm. The area is drained by the Triftwasser ...
Fox Glacier, New Zealand. A serac (/ s ɛ ˈ r æ k ˌ ˈ s ɛ r æ k /) (from Swiss French sérac) is a block or column of glacial ice, often formed by intersecting crevasses on a glacier. Commonly house-sized or larger, they are dangerous to mountaineers, since they may topple with little warning. Even when stabilized by persistent cold ...
Sep. 23—A group of visitors in Glacier National Park used bear spray to ward off a grizzly after it bit a Washington man last week as they hiked through foggy conditions along the popular ...
When the pillow lavas break off and roll down the volcano slopes, pillow breccia, tuff breccia, and hyaloclastite form. The meltwater may be released from below the ice as happened in Iceland in 1996 when the Grímsvötn caldera erupted, melting 3 km 3 of ice and giving rise to a large glacial lake outburst flood .
