Series of Strong Aftershocks rattle Christchurch after New Zealand quake
John Key has said it was a "miracle" that no-one was killed
A series of aftershocks have rattled Christchurch, New Zealand,
following a powerful 7.0-magnitude earthquake.
A curfew imposed overnight between Saturday and Sunday has been lifted,
but parts of the city remained cordoned off, Radio New Zealand said.
Police said the curfew was intended to protect people from falling
debris, as the quake caused significant damage.
The mayor of the city, Bob Parker, described the damage as immense, and
a state of emergency has been declared.
Gale force winds were forecast for Sunday, and authorities have warned
that these may affect unstable buildings.
New Zealand's Civil Defence estimated that more than 500 buildings had
been damaged.
Local officials say power has been largely restored and tankers will
supply water.
There are thousands of earthquakes in New Zealand every year, but very
few do any damage.
'Unsafe'
During the night following the earthquake, 19 aftershocks were reported
by the GeoNet website.
One family in Darfield, near the epicentre of the quake, reported
spending the night under their dining table.
The earthquake struck New Zealand's South Island in the early hours of
the morning when most people were asleep.
The epicentre was 20km (13 miles) west of Christchurch, according to
New Zealand's government-owned research organisation GNS Science.

Two men were seriously injured by falling masonry and glass, but there
have been no reports of fatalities.
"The damages are incredibly frightening. The only thing you can say
it's a miracle that no-one lost their life," Prime Minister John Key
told TV NZ.
Many homeowners faced a cold winter's night and leaking or damaged
homes. Hours after the quake, one building in the Christchurch city
centre burst into flames, following a suspected gas leak.
Mayor Bob Parker said the "sharp, vicious earthquake" had caused
significant damage in parts of Christchurch.
He said daylight showed that the damage was considerably worse than
first thought.
"There would not be a house, there would not be a family in our city
that has not in some way had damage done to their person, to their
property," he said on national radio.
"I think it's like an iceberg; there is... below the visible line,
significant structural damage."
'Terrifying'
Police said damage and power outages had been reported as far afield as
Dunedin, 360km (223miles) to the south-west.
Chimneys and walls had fallen from older buildings, with roads blocked,
traffic lights out and power, gas and water supplies disrupted, Mr
Parker said.
"There is considerable damage in the central city and we've also had
reports of looting, just shop windows broken and easy picking of
displays," police inspector Mike Coleman told Radio New Zealand. "It's
very unsafe to be out and about."
Susan Birkbeck, who lives in the centre of Christchurch, told the BBC:
"It was absolutely shocking, we're all terrified and scared of what's
going to happen next."
A damaged building and a building on fire in Christchurch, New Zealand,
on 4 September, 2010 Daylight showed extensive damage
"I was asleep when suddenly the house started shaking and there was
this smashing sound, I thought a large truck had just driven through
the front window."
"I'm now sitting on my bed surrounded by broken glass and I've no idea
what to do. The walls and roof are just hanging, it's terrifying," she
added.
The local newspaper, The Press, said the quake was felt widely across
the South Island, including Christchurch and the nearby port city of
Timaru.
New Zealand lies at the southern end of the so-called Pacific Ring of
Fire, and above an area of the Earth's crust where the Pacific Plate
converges with the Indo-Australian Plate.
The country experiences more than 14,000 earthquakes a year, of which
only around 20 have a magnitude in excess of 5.0.
The last fatal earthquake was in 1968, when a 7.1-magnitude tremor
killed three people on the South Island's western coast.
