Christchurch continues to be rocked by aftershocks this afternoon, with a staggering 41 earthquakes recorded in the Canterbury region over the past 24 hours.

A swarm of large aftershocks, including a violent magnitude 5.5, rattled the city overnight and knocked out power to thousands of homes.

There have been no reports of significant damage or injury, but it was a sleepless night for most residents as 14 aftershocks – all above 3.3 magnitude – struck at regular intervals between 10.31pm and 9.01am.

The latest shake was a magnitude 3.9 at 12.28pm, at a depth of 15km and located 20km east of Christchurch.

Popular website 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 mag 6.0 December 23 shake is ranked fourth biggest.

Early morning quakes rattle Christchurch

More Christchurch residents could be leaving town for good if the quakes continue.

A swarm of large aftershocks which rocked Christchurch overnight and knocked out power to thousands of homes has not caused any new damage to the rattled city, authorities say.

The shaky start to what Cantabrians hoped would be a calm 2012 included a violent magnitude-5.5 quake at 5.45am felt across the region.

Geonet reported two earthquakes striking at 5.45am, just seconds apart, and of similar magnitude, which would account for the surging nature of the early-morning jolt.

It was centred 20km north-east of the port of Lyttelton at a depth of 15km and follows a similar pattern to the latest bout of aftershocks kick-started by the swarm of December 23 shakes, which included a mag-6.0.

Between 10.31pm last night, when there was a mag-3.4 shake, and 9.01am this morning, Christchurch has been rocked by a reported 14 aftershocks – all above 3.3-mag.

After the 5.45am shake, power was cut to 10,000 homes across several eastern suburbs, including Shirley, Burwood, Dallington, Richmond, and Spencerville.

A spokesman for Orion Energy said power was restored at 7.41am.
