A strong quake hit New Zealand's second-biggest city of Christchurch on Tuesday for the second time in five months, toppling buildings, causing "multiple fatalities," trapping people beneath rubble and sparking fires.
Local TV showed bodies being pulled out of rubble strewn around the city center, though it was unclear whether any of them were alive, but police reported multiple fatalities after the 6.3 magnitude quake struck during the busy lunchtime.
"I was in the square right outside the cathedral - the whole front has fallen down and there were people running from there - there were people inside as well," said John Gurr, a camera technician who was in the center of the city when the quake hit.
"A lady grabbed hold of me to stop falling over ... It's not nice at all. We just got blown apart. Colombo Street, the main street, is just a mess ... There's lots of water everywhere, pouring out of the ground - its liquefaction - it's an absolute mess."
Silt, sand and gravel
Christchurch is built on silt, sand and gravel, with a water table under it. In an earthquake, the water rises, mixing with sand.
Unlike last year's even stronger tremor, which struck early in the morning when streets were virtually empty, the streets, shops and offices in the city of almost 400,000 were thronged with people when the shallow tremor struck.
It hit at 12:51 pm (2351 GMT Monday) at a depth of only 4 km (2.5 miles), according to the U.S. Geological Survey's Web site.
"It's huge, it's just huge," a priest told a TV reporter outside the remains of the city's stone cathedral, part of which had been reduced to a pile of large sandstone blocks.
"I just don't know whether there are people under this rubble," he said, before he appeared to add in a quiet voice: "I think so."
Prime Minister John Key, who called an emergency cabinet meeting for later in the day, told parliament: "This is a very populated time with people at work and children at school. Sadly, I cannot rule out whether there have been fatalities or not. But we are aware of significant damage to buildings that had people in them at the time."
News of the quake helped send the New Zealand dollar to as low as $0.7541, down about 1.2 percent from late U.S. levels on fears the damage could dent confidence in the already fragile economy.
The tremor was centered about 10 km (six miles) southwest of Christchurch, which had suffered widespread damage during last September's 7.1 magnitude quake but no deaths.
"There has been a lot of damage, our TVs have been smashed and there are big cracks in the house. Neighbors have lost brick fences," Nicholas Hextall, who lives in central Christchurch, said by phone. Power and water had been cut.
The region has been struck by thousands of aftershocks since the original quake.
New Zealand, which sits between the Pacific and Indo-Australian tectonic plates, records on average more than 14,000 earthquakes a year, of which about 20 would normally top magnitude 5.0.
The recent earthquakes and volcanic activity spiking along the ring of fire seemed to start up at the Kamchatka Penninusla, then move south past China, Japan, through Indonesia, Malaysia and the Phillipines, down around the northern and eastern eastern coast of Australia, finally ending with two quakes in the New Zealand area. As with previous earthquakes in the South Island area, the quakes were preceeded by another whale beaching and more unusual animal die-off activity, due to the electromagnetic discharging of these non-viscous geoplasma earthquakes. It seems there is a lot of major geoplasma movement under the Pacific Plate, as if it started to crack, shift and and heave at the north west corner, and then carry this motion southward. I hope the death toll and casualties are minimal in Christchurch, and my prayers are with anyone now residing along that Pacific Plate margin.
