Shocking giant GLACIER CALVING generates a huge tsunami-like wave at Glacier National Park in Argentina.
Ice calving, also known as glacier calving or iceberg calving, is the breaking of ice chunks from the edge of a glacier. 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. The ice that breaks away can be classified as an iceberg, but may also be a growler, bergy bit, or a crevasse wall breakaway. Calving of glaciers is often accompanied by a loud cracking or booming sound before blocks of ice up to 60 meters (200 ft) high break lose and crash into the water. The entry of the ice into the water causes large, and often hazardous waves. The waves formed in locations like Johns Hopkins Glacier can be so large that boats cannot approach closer than 3 kilometers (1.9 mi). These events have become major tourist attractions in locations such as Alaska. Many glaciers terminate at oceans or freshwater lakes which results naturally in the calving of large numbers of icebergs (Learn more here: https://en.wikipedia.org/wiki/Ice_calving )
