A swarm of large aftershocks, including a violent magnitude 5.5, rattled the Christchurch overnight and knocked out power to thousands of homes. Christchurch continues to be rocked with 41 earthquakes recorded in the Canterbury region over the past 24 hours. There have been no reports of significant damage or injury, but it was a sleepless night for most residents. After the 5.45am tremor, power was cut to 10,000 homes across several eastern suburbs, including Shirley, Burwood, Dallington, Richmond, and Spencerville.
There were no reports of liquefaction or residential damage. The Canterbury Earthquake Recovery Authority (Cera) said there had not been any further "significant'' damage. GNS reported that the faults offshore are short in length and not likely to generate a significant tsunami. The sea inundation to land is low risk, probably not more than a storm surge. (NZ Herald)
Quakelive ranked the 5.5 quake at 5.45am as the 11th largest to hit the city since the 7.1 magnitude tremor on September 4, 2010. The magnitude 6.0 December 23 shake is ranked fourth biggest.
