Subject: New Zealand hit by earthquake

http://edition.cnn.com/2011/WORLD/asiapcf/02/21/new.zealand.earthquake/?hpt=T2 (CNN) -- A 6.3-magnitude earthquake in Christchurch, New Zealand, Tuesday afternoon, seriously damaged the city's cathedrals, burst water mains, buckled streets and shut down phone service, according to media reports from the region. The U.S. Geological Survey said the quake struck just before 1 p.m. Tuesday (7 p.m. Monday ET), and a 5.6-magnitude aftershock struck about 15 minutes later. The New Zealand Herald reported that phone lines in the area were out, roads were cracked -- in some cases lifted as much as a meter -- and water mains had burst, flooding several streets. Christchurch police told TVNZ that the city's 106-year-old Cathedral of the Blessed Sacrament was badly damaged, and a Herald reporter said that half of the building had collapsed. TVNZ reported that the 147-year-old Christchurch Cathedral's spire had toppled, Christchurch Hospital was being evacuated and the airport was closed. The quake caused significant damage to several older buildings, the Herald reporter said. Christchurch Mayor Bob Parker told Radio New Zealand that the rumbling tossed him across the room, that he knew of injuries in the city council building and has heard unconfirmed reports of serious injuries. "That was, in the city central anyway, as violent as the one that happened on the 4th of September," he said. Parker added that streets were jammed as people tried to get out of the city, and he urged people to avoid the water supply. "We've been through this before this once, we now need to think what we did at that time," he said. Southern New Zealand has been plagued by a series of quakes since September, when the area was shaken by a 7.1-magnitude temblor that New Zealand authorities said was the most damaging quake to hit the region since 1931. The earthquake struck in the predawn hours of September 4, and authorities said the deserted streets at that time likely kept injuries to a minimum. There were no deaths from that earthquake. Both the Roman Catholic Cathedral of the Blessed Sacrament and the Anglican Christchurch Cathedral were undergoing repairs after being badly damaged by the September quake. "The quake is significantly smaller than the previous Christchurch earthquake, however it was very shallow and might have been very close to the center of the city," Civil Defense spokesman Vince Cholewa told the New Zealand Herald. TVNZ also reported that its newsroom in Christchurch was badly damaged. ======================================================= From CNN International ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^6 I hope that the news is not as bad as I fear it is.

5 km from city CBD

4km down

its caused more damage than the 7.1 experienced just recently

Hopefully the US Navy is on the way to provide assistance. A carrier could supply water, electricity, and medical assistance as needed. NZ probably doesn't need much help but I'm sure the water generator and helo Lift capability would be beneficial.
May not see eye to eye with NZ politics but when push comes to shove they are friends.

The impact of yesterday's quake far exceeds the semptember 7.1 quake, as it struck just after midday in the CBD causing damage to the office "towers"...
 
65 reported deaths so far...
 
First disaster deployment of the HMNZS Canterbury MultiRole Vessel.
 
thanks for the concerns

That is horrible.
 

 
After the Indonesia disaster, I was proud of my nation's efforts. THIS minuscule and miserly offer makes me ashamed. We can do more. My apologies to the victims and condolences for their losses and suffering.
 
I hope and pray the rest of the world steps up. From what I see, Christchurch needs help.

the kiwis have used one of their naval vessels in the past to provide backup power when they had some power station problems, so they've done it before.
 
HMNZS Canterbury will be a needed asset - esp if they run short of medical facilities

There is no need to apologise, any offer off help is greatly appreciated. On behalf of my country I offer our thanks.
Australia already has emergency response teams on the ground here - again Thank You.
 
The problem with Electricty syupply from a Ship, is the Port is located quite some distance from the city.
 
Fresh water is currently being tanked in by milk tankers (something we have plenty off).
 
National State of Emergency has been declared.
 
But, Christchurch Airport is now open to international flights.
 
Again, i cannot say this enough - thank you for the support.

Unfortunately the long standing policy of the NZGovt and the USN with regard to Nuclear ships would need to be ignored for this to occur...

you're getting fuel supply problems as well, army and airforce might need to start considering the deployment of fuel bladders in some of the regionals....

Why Was New Zealand's Latest Earthquake So Deadly?

Christchurch copes with a tragedy it did not see coming

New Zealanders living in the city of Christchurch (population 377,000) on the South Island's Canterbury Plains were hit hard Tuesday by 6.3-magnitude earthquake, an aftershock from September's 7.1-magnitude quake. Prior to these two seismic events, Canterbury Plains likely had not experienced an earthquake in thousands of years. In fact, scientists did not even know there was a geological fault there until it ruptured last year.

The latest Christchurch tremors were not as strong as the original earthquake, but they have caused considerably more damage and claimed dozens of lives (no one died during the September quake). The Christchurch epicenter was only 10 kilometers outside of the city, whereas the 2010 seismic event took place about 40 kilometers to the west, where there is mostly farmland. Adding to Christchurch's misfortune, the aftershock struck only about four kilometers in depth below the city, whereas September's seismic event originated about 10 kilometers down. Compounding these problems, Tuesday's quake hit during lunchtime, when the city was buzzing with activity, whereas the earlier disaster occurred during early morning hours.


Scientific American
spoke with Robert Yeats, a professor emeritus of geology at Oregon State University in Corvallis, about why earthquakes are so difficult to predict and what is being done to even the odds.

[
An edited transcript of the interview follows.]

The 7.1-magnitude earthquake in September caught the locals completely off guard. Why was that earthquake, as well as Tuesday's aftershock, such a surprise?

The earthquakes struck an area of New Zealand's South Island where sediments are deposited from the Southern Alps and from the nearby rivers. The sediment deposits reach all the way to the east coast on what is called the Canterbury Plains. The fault that ruptured in September had not done so in thousands of years, during which sediments had been deposited on top. I've been out there, and it's like driving anyplace where it's all flat. There are farms, but there's nothing that says, "Here's a fault." So when the earthquake struck in September, they were totally surprised. On the South Island, the Hope Fault and Marlborough Fault System are better known—there had been an earthquake in 1888 along the Hope Fault. Much less was known about faulting on the Canterbury Plains because no earthquake had happened in their historical record.

What defines an "aftershock" as opposed to an earthquake? Does a certain amount of time have to elapse for a seismic event to be considered an earthquake?

It takes many years before seismic activity can be considered an earthquake rather than an aftershock of a previous earthquake. That's a point of debate among seismologists. If you lo
