Earthquake shakes Tasman Glacier loose

The tragic New Zealand earthquake of February 22, which hit Christchurch hard, had an interesting side effect, which was to cause a major calving event off the Tasman glacier. The falling ice caused a 12-foot-high lake tsunami in Lake Tasman, the lake that is at the Tasman Glacier outlet.
