Massive iceberg shears off after N. Zealand quake

A 30 million tonne block of ice sheared off a New Zealand glacier just minutes after a violent earthquake devastated the city of Christchurch, officials said Wednesday.

The huge iceberg crashed into a lake shortly after the 6.3 magnitude tremor rocked the South Island on Tuesday and created waves up to three metres high for 30 minutes which rocked two sightseeing boats on the lake at the time.

The enormous iceberg -- estimated to weigh 30 to 40 million tonnes -- began ripping off the Tasman Glacier at Aoraki Mount Cook National Park accompanied by a loud noise which sounded like a rifle shot, a local tourism official said.

Aoraki Mount Cook Alpine Village tourism manager Denis Callesen said locals had been expecting a major iceberg to drop from the glacier for the past month, but the "curve ball" was that the event was caused by an earthquake.

"The earthquake that we felt here was a swaying motion for about a minute, then it stopped and then it swayed for about another minute," he told AFP.
