She along with so many others, walked down the main street for a few miles to get out of the building zone, and eventually she wound up meeting some locals who took her in and allowed her to stay in their home for a couple of days until the airport was up and running again and she could leave. She said the compassion that was shown to each other and to the foreign tourists was exceptional and if she could do it over again, she would still be in New Zealand that day, even having to go through the quake, simply because of the people.
I echo the sentiments of the lady from Atlanta. While I was not there during the quake or time of a disaster, I can say that my travels all over New Zealand were met with such warmth from the people of New Zealand. It was the whole package, the beauty of the country teamed with the kindness of the citizens that make it such a wonderful place!

Thats not realistic from a cost perspective especially with hundreds of structures green stickered ok in the CBD. They will rebuild the CBD where it is but work on new ground stabilistion techneques and obviously use advances in building designs.

Also pays to remember the damaging fault is generally not active and the major alpine fault would do far less damage in comparison.

I've visited NZ but never lived there so maybe I'm way off on this but I'd always had the impression that the entire country -- like, say, Iceland, Chile or Japan -- is seismically active and that there was no place that's safe from quakes. But, from posts in this thread, it seems that perhaps the north part of North Island and, until now, Christchurch were considered less susceptible to quake activity? If that's the case then having two big quakes rock ChCh in a matter of months must've been especially emotionally shattering.

The main fault line runs up along the Southern Alps of the South Island, up into the North Island entering through Wellington and the Hutt Valley, through Taupo and exits the country through the Bay of Plenty. So the north of the North Island would not be as seismically active. However Auckland is built on a volcanic area although extinct.

Although Christchurch was not seen to be a huge risk, the risk still existed as does in all parts of NZ. The main focus is on the main alpine fault, described above which is about 100km to the west of ChCh, so when that goes it is likely to impact ChCh again, although hopefully not to the extent that these past couple of quakes have.

As a matter of interest we had a 4.8 aftershock last night about 7-30 which was quite a shake - enough to get us back under door frames in a hurry! Also Christchurch Quake Map has a facebook page with lots of interesting comments and information in it.

So Auckland is in a bit less danger than Wellington? Interesting. I didn't know that.

Today they buried a 6 month old child killed in the Christchurch quake. This was a nasty quake that unfortunately hit directly in the city as opposed to the perimeter or countryside. Their economy can support recontruction ,but nobody can replace the lives lost. I'm presently trying to understand
dormant faults (except Yellowstone)ie 125th Street New York fault,the nearly 1600 <3.8 mag quakes in Yellowstone since January 17. The New Madrid fault in the Midwest is raising eyebrows. Some predict it could reverse the flow of the Mississippi and flood six states. They have special significance and people near these areas must be prepared for potential longterm survival on their 2nd floor or roof if Red Cross is overwhelmed. Yellowstone is capping at 3" per year a and
it's notorious (worlds lagest magma chamber could blow as we speak.) Most of us know the major faults although additional monsters lie on the oceans floors and pose a whole bunch of added activity not withstanding tsunamis .

I think sometimes people don't think about earthquakes much because a lot of these places can be dormant for hundreds of years. I was reading that once the Christchurch area calms down, it could be another 1000 years before another big quake hits.

The New Madrid fault is probably going to blow again and when it does, it will make hurricane katrina look like a minor issue.

Yea agree, geologists believe thousands of years between these fault movements that effected Christchurch.

That New Madrid fault in the States is huge, but probably wouldn't slip all at once though. The Californian faults seem to get all the attention, are people in the Mid West prepared?

In a word, no.

New Madrid Seismic Zone Earthquake Hazard Article and Map

Money quote:

"The City of Memphis and the surrounding metropolitan area of more than one million people would be severely impacted. Memphis has an aging infrastructure, and many of its large buildings, including unreinforced schools and fire and police stations, would be particularly vulnerable when subjected to severe ground shaking. Relatively few buildings were built using building codes that have provisions for seismic-resistant design. Soil liquefaction and related ground failures are likely to occur in downtown Memphis along the Mississippi River and along the Wolf River that passes through Memphis. The older highways and railroad bridges that cross the Mississippi River, as well as older overpasses, would likely be damaged or collapse in the event of a major New Madrid earthquake. Some of the bridges and pipelines crossing the Wolf River might be damaged or destroyed. Although Memphis is likely to be the focus of major damage in the region, St. Louis, Mo., Little Rock, Ark., and many small and medium-sized cities would also sustain damage."
