Christchurch Earthquake 2011
A swarm of earthquakes, including a magnitude 6.0 and two greater than magnitude 5.0, have hit Christchurch, toppling already damaged buildings, injuring residents and disrupting power, phone services and retailers.
The magnitude-6.0 quake, which struck at 3.18pm, was six kilometres deep and centred 10km north of Lyttelton, Geonet said.
It was larger than the magnitude-5.8 tremor that shook the city at 1.58pm, causing widespread panic and damage.
A 5.3 quake hit at 2.06pm. It struck 20km east of Belfast at a depth of 10km.

STATE OF EMERGENCY NOT PLANNED
Christchurch deputy mayor Ngaire Button said a state of emergency was not planned.
The city council urged people to take care of their families and stay home if possible.
Further damage had been seen by a helicopter crew of the western wall of the Christ Church Cathedral, along with some other buildings in the central city.
Roads and other infrastructure were still being assessed.
Some Avon River stopbanks were damaged, but no breaches had been recorded. There was no need to boil water at this stage.
No welfare centres had been opened, but Windsor School would open later in the day if needed.
Owners of commercial buildings were asked to check their buildings before staff were allowed to return.
Civil Defence teams would doorknock homes in the east tonight and would have identification, Button said.
CATHEDRAL ROSE WINDOW COLLAPSES
The Christ Church Cathedral Rose Window had completely collapsed and more cathedral damage was feared, Dean Peter Beck said.
"We don't know the rest of the damage. It was already very seriously damaged and it will be further damaged again," he said.
Beck said the new quakes were a "huge emotional shock".
"We were starting to get traction again and now it feels like June 13 again," he said.
The Christchurch Arts Centre suffered minor damage.
Centre director Ken Franklin said a few gables had collapsed, but there was no "substantial damage that was obvious".
A St John spokesman said ambulance communications had received up to 150 111 emergency calls since the first quake.
Staff had assessed and treated about 60 patients with minor quake-related injuries or issues, he said.
A police spokesman said Windsor House Rest Home residents in New Brighton were reported to be trapped on the second floor, but were being evacuated by the Fire Service.
The Coastguard rescued four people trapped at Boulder Bay near Godley Head.
One person was reported to have been injured at the Eastgate Shopping Centre and had been taken to Christchurch Hospital, the police spokesman said.
A woman at the Northlands Shopping Centre fell and injured her stomach, but did not require medical treatment.
FRESH DAMAGE IN THE CITY
There were significant rockfalls at Redcliffs, and a stopbank in New Brighton Rd collapsed.
A partly demolished building on the corner of Barbadoes and Kilmore streets has fallen, and a vacant house at 81 Aynsley Tce collapsed.
A red-stickered house in Oram Ave, New Brighton, also collapsed.
Significant flooding and liquefaction has hit the eastern suburbs, including Avonside, Bexley, Retreat Rd and Bower Ave.
Part of a Scarborough rockface collapsed, but the rock was held by shipping containers at the bottom of the cliff.

Damage has been reported to the Work and Income building in New Brighton, with all staff safely evacuated.
A stopbank in Kaiapoi is damaged and the India Blue restaurant in Sumner is damaged and has been cordoned off.
A building on the corner of Charles St and William St in Kaiapoi is at risk of collapse.
Police are urging people to stay away from hill suburbs because of risk of rockfalls.

Canterbury Earthquake Recovery Authority (Cera) chief executive Roger Sutton said he had flown around the city and saw liquefaction similar to the September quake.
Christchurch International Airport chief executive Jim Boult said flights would restart at 6pm.
The airport was closed for engineering checks after the first quake. Some flights were diverted and cancelled.
POWER AND PHONES OUT
Orion chief executive Rob Jamieson said this evening that power was now back on in rural areas, but about 19,000 customers were still without power in the eastern suburbs.
They hoped most of the outages were caused by "tripping" and not cable damage, he said.
Phone networks are down and Telecom has asked residents to keep mobile calls for emergency use where possible, and use text messages.
NO CHRISTMAS EVE MAIL
There will be no mail deliveries in the Christchurch area by New Zealand Post tomorrow.
The Christchurch Mail Centre has been evacuated as a precaution for the safety of staff and will not reopen for processing tonight.
The next scheduled New Zealand Post mail deliveries following the statutory holidays will be December 28.
Post shops will be open tomorrow on a case-by-case basis at the discretion of individual store managers.
COUNCIL BUILDINGS CLOSED
All council buildings have been closed until they can be assessed as safe to occupy.
Christchurch Mayor Bob Parker, who was holidaying in Taupo, was trying to get back to the city.
He said the quake was another setback physically and psychologically.
"Coming almost on Christmas Eve, with all the shops shutting, malls evacuated and airports closed, and people sitting around in tears ... you just can't underestimate the ongoing stress this has created for so many people,'' he told Television One.
"It's just going to be one hell of a day and my heart just breaks really to think so many people have already been so much.''
DISTRICT HEALTH BOARD
Burwood Hospital is operating on emergency power and the birthing unit at Burwood Hospital has been temporarily relocated. Mothers who go into labour and had planned on giving birth at Burwood are asked to attend Christchurch Women's Hospital instead.
Christchurch City Council have reported that some sewage discharge to the Heathcote estuary has occurred. Residents are advised to avoid contact with the estuary until at least 4pm on Sunday, providing there are no further aftershocks.
