Tourists on a boat watch an iceberg, broken off from the glacier after Tuesday's earthquake, in the Tasman Lake, 200km (124 miles) southeast of Christchurch in this handout photograph released February 23, 2011. The 6.3 magnitude earthquake that struck New Zealand on Tuesday, killing at least 75 people in Christchurch, also shook loose 30 million tonnes of ice from the nation's longest glacier, sending boulders of ice into a nearby lake.
