The Patagonian glacier drops large amounts of ice about every four years. The last rupture was in 2012. Partial breaks occurred in February, indicating a large collapse could happen soon.
Ice calving, also known as glacier calving or iceberg calving, is the breaking of ice chunks from the edge of a glacier. [1] It is a form of ice ablation or ice disruption . It is the sudden release and breaking away of a mass of ice from a glacier , iceberg , ice front , ice shelf , or crevasse .
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]
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.
An Antarctic glacier the size of Florida is on the verge of collapse, scientists with the American Geophysical Union warned Monday, a nightmare scenario made worse by climate change that could ...
A23a is a large tabular iceberg which calved from the Filchner–Ronne Ice Shelf in 1986. It was stuck on the sea bed for many years but then started moving in 2020. As of January 2025, its area is about 3,500 square kilometres (1,400 sq mi), which makes it the current largest iceberg in the world.
In 2018 or 2019, a large chunk almost 14 km × 8 km (9 miles × 5 miles) broke off and was named A-68B, with the mother iceberg now being A-68A. [13] On 6 February 2020, A-68A began moving into open waters. [14] On 23 April 2020, a chunk measuring about 175 sq. km. (70 sq. mi.) broke off the iceberg and was named A-68C. [15]
