New Zealand's powerful earthquake that smashed buildings, cracked roads and twisted railway lines around Christchurch ripped a new 11ft wide fault line in the earth's surface, a geologist said today.

Canterbury University geology professor Mark Quigley said what 'looks to us that it could be a new fault' had ripped across the earth and pushed some surface areas up.

The quake was caused by the continuing collision between the Pacific and Australian tectonic plates, said Prof Quigley, who is leading a team trying to pin down the temblor's source.

'One side of the earth has lurched to the right... up to 11 feet and in some places been thrust up,' he told National Radio.

'The long linear fracture on the earth's surface does things like break apart houses, break apart roads. We went and saw two houses that were completely snapped in half by the earthquake.'

At least 500 buildings, including 90 properties, were designated as destroyed in the 7.1-magnitude quake that struck on Friday near the South Island city of 400,000 people. Most other buildings sustained only minor damage.

The quake cut power across the region, roads were blocked by debris and gas and water supplies were disrupted, but Christchurch mayor Bob Parker said services were being restored today.

Power was back to 90 per cent of the city and water supply had resumed for all but 15 to 20 per cent of residents, he said. Portable toilets had been provided and tanks of fresh water placed around the city.

Mr Parker said it would take a long time to fully fix some core services such as water and sewerage. 'Our first priority is just people,' he said. 'That's our worry.'

Up to 90 extra police officers had flown in to Christchurch to help and troops were likely to join the recovery effort tomorrow, he said.

Today specialist engineering teams began assessing damage to all central city buildings, said Paul Burns of the city's search and rescue service.

Officials said schools across the region would remain closed for the next two days to allow time to check whether they were safe.

Only two serious injuries were reported from the quake as chimneys and walls of older buildings were reduced to rubble and crumbled to the ground. Prime Minister John Key said it was a miracle no one was killed.

Part of the reason the city escaped major injuries was because the quake happened before dawn local time, Mr Key said.

'If this had happened five hours earlier or five hours later there would have been absolute carnage in terms of human life,' he told TV One News Sunday.

Roger Bates, whose dairy farm at Darfield was close to the quake's epicentre 19 miles west of Christchurch, said the new fault line had ripped up the surface across his land.

'The whole dairy farm is like the sea now, with real (soil) waves right across the dairy farm. We don't have physical holes (but) where the fault goes through it's been raised a meter or meter and a half,' he said.

Experts said the low number of injuries in the powerful quake reflected the country's strict building codes.

'Thank God for earthquake strengthening 10 years ago,' Anglican Dean of Christchurch the Rev Peter Beck said.

Euan Smith, professor of Geophysics at Victoria University, speculated that the very soft soils of Christchurch had 'acted like a shock absorber over a short period...

doing less damage to smaller buildings'.

Mr Key, who flew to Christchurch to inspect the damage, said it was 'an absolute miracle' that no one had died.

He said the city 'looks like something off a movie set', with wrecked buildings, buckled roads, ruined water mains and sewerage systems and some flooding caused by broken water pipes.

Rebuilding infrastructure such as roads, water and sewerage systems 'would be a major cost' that the government would have to meet, he said.

Canterbury Emergency Management Office manager Jon Mitchell said the central city would remain cordoned off with no public access before today, except for inner-city residents.

Scientists from GNS Science began installing extra seismographs in the region to record seismic data from the continuing stream of aftershocks rocking the region.

More than 60 had been recorded by today.

Up to 40 portable seismographs were being set up, including some due from Stanford University in the US, the agency said.

Seismologists study aftershock sequences to help learn more about the mechanics of the main shock and rupture, and to check whether stress in the earth's crust has been transferred to other faults in the region.

New Zealand sits above an area of the Earth's crust where two tectonic plates collide. The country records more than 14,000 earthquakes a year - but only about 150 are felt by residents. Fewer than 10 a year do any damage.
