The quake at a depth of 34 kilometres (21.1 miles) struck six kilometres (four miles) from Christchurch at 04:05 am (1635 GMT Friday), the USGS said.
A 7.0 magnitude earthquake rocked New Zealand's second largest city Christchurch early Saturday, causing widespread damage including the collapse of some buildings and power outages, witnesses and the U.S. geological survey said. The Civil Defence ministry said the national crisis management centre had been activated. "We've had a wide range of reports of some serious damage," a civil defence spokesman said.

Although many people with minor injuries sought treatment, hospitals said there were no reports of any serious injuries although doctors were on standby because of the intensity of the quake and the damage to buildings.

The quake struck at a depth of 16.1 kilometres some 30 kilometres northwest of Christchurch at 4:35 a.m. (11:35 a.m. ET Friday), the USGS said.

Roads in the seaside suburbs were packed with cars as residents moved inland but there were no tsunami alerts issued. A swarm of aftershocks were ongoing and police said damage was widespread throughout Christchurch, with electricity supplies cut to about half of the city of about 340,000.

Sewer lines were damaged and residents were being urged to conserve water supplies. Local resident Colleen Simpson told the Stuff website that many people had run out onto the streets in fear, while the mobile phone network was failing.

"Oh my God. There is a row of shops completely demolished right in front of me," Simpson said. Kevin O'Hanlon, from Mairehau in Christchurch, said: "Just unbelievable. I was awake to go to work and then just heard this massive noise and, boom, it was like the house got hit. It just started shaking. I've never felt anything like it."

The Galeras Volcano
Authorities and inhabitants in the south of Colombia fear an eruption of the Galeras volcano after four tremors shook the area on Sunday and Monday.

According to the volcanic observatory run by Colombia's Geology and Mining authority Ingeominas, the several tremors are related to the activity of the volcano and an eruption is likely within days or weeks.
The quakes took place in the area surrounding the active volcano just outside the city of Pasto.

Ingeominas says it continues to be alert to the volcanic phenomena and will report changes.

The Galeras volcano erupted last in January, after which 8,000 people were forced to evacuate.

Scientists: Rare Double Quake Caused Deadly Samoa Tsunami

Stunned survivors search for bodies amongst the debris left by the tsanami on Lalomanu Beach in September 2009.
Wellington - The devastating tsunami which killed nearly 200 people in Samoa and Tonga last September was the result of a rare double earthquake and not one as previously believed, scientists said Wednesday.

Simultaneous earthquakes, with one hiding the other, are unusual "and almost certainly increased the size of the tsunami and its destructiveness on some Tongan islands," New Zealand's GNS Science said in a statement.

Global earthquake readings initially indicated a single large "normal faulting" quake of magnitude 8.0 had occurred, producing an extensional motion while the tsunami waves indicated a "thrust" event with compressional movement.

The scientists said they were unable to reconcile the conflicting data until six weeks after the event when measurements from a small Tongan island showed there must have been two large earthquakes.

Their findings appear this week as the cover story in the prestigious science publication Nature.

"This is a rare phenomenon," lead author John Beavan, a geophysicist at GNS Science, said Wednesday.
