5 acres glacier lake dries out in 2 months, chile
SANTIAGO, Chile
The melting of nearby glaciers or cracks in the ground caused by an
earthquake were proposed by scientists Thursday as possible causes for
the disappearance of a five-acre glacial lake in southern Chile...
As glaciers retreat, glacial lakes form behind natural dams of ice or
moraine, earth and stones pushed up by a glacier. These relatively weak
dams can be breached suddenly, causing the lake to drain. Possible
causes for the dam to be breached include a sudden input of water into
the lake, an earthquake or avalanches of ice or rock.
