2010 Canterbury earthquake

The 2010 Canterbury earthquake struck the South Island of New Zealand with a moment magnitude of 7.1, and had a maximum perceived intensity of X (Extreme) on the Mercalli intensity scale. The earthquake caused widespread damage and several power outages, particularly in the city of Christchurch, New Zealand's second largest city at that time. Two residents were seriously injured, one by a collapsing chimney and a second by flying glass. One person died of a heart attack and another form a fall. Mass fatalities were avoided partly due to there being few houses of unreinforced construction.
