2011 Christchurch earthquake
The February 2011 Christchurch earthquake occurred on 22 February at 12:51pm local time (23:51 21 February UTC) and registered 6.3 on the Richter scale. The earthquake struck the Canterbury Region in New Zealand's South Island and was centred 2 kilometres (1.2 mi) west of the port town of Lyttelton, and 10 kilometres (6 mi) south-east of the centre of Christchurch, at the time New Zealand's second-most populous city. The earthquake caused widespread damage across Christchurch, killing 185 people in the nation's second deadliest natural disaster.Christchurch's central city and eastern suburbs were badly affected, with damage to buildings and infrastructure already weakened by the magnitude 7.1 Canterbury earthquake of 4 September 2010 and its aftershocks. Significant liquefaction affected the eastern suburbs, producing around 400,000 tonnes of silt. The earthquake was felt across the South Island and parts of the lower and central North Island. While the initial quake only lasted for approximately 10 seconds, the damage was severe because of the location and shallowness of the earthquake's epicentre in relation to Christchurch and previous quake damage. Subsequent population loss saw the Christchurch main urban area fall behind the Wellington equivalent to decrease from second to third most populous area in New Zealand.
