miracle is not just luck, of course, this is New Zealand's population density, such as building structure and supervision are closely linked. Although the Christchurch City is New Zealand's second largest city, but only about 40 million population, population density is relatively low, and the residents are living in a two-story house, house collapses caused by damage to the residents is also more small.

as earthquakes, New Zealand building standards for housing and very strict, but also through legislation to ensure the quality of infrastructure construction. Wenchuan after the earthquake, the quality of collapsed school buildings had suffered criticism, some inside the concrete structure, or even replaced with steel wire reinforcement. The New Zealand building codes, for investors, designers and design details are provided: the drawings to be sent to specialized departments for review; construction supervision of architects and designers. Victoria University of Wellington School of Architecture Associate Professor Andrew. Charles Allison (Andrew Charrison) explains: the responsibility of government censors,
Kennedy wrote in a blog. In addition, due to the earthquake's epicenter from the Christchurch City and 50 kilometers, is not a Epicentral earthquake was first proposed by Japanese scholars, refers to the underground in large cities and around the earthquake, the city's dangerous. Tangshan earthquake of 1976 belongs to epicentral earthquake.
local time at 4:35 on the 4th, the largest South Island city of Christchurch, New Zealand people by surprise. Collapsed buildings all around, broken cables, broken glass and cars were smashed, some supermarkets and all of the items 被震 fell to the ground, and the scene is a mess.

New Zealand isolation technology in the world leading level. City builders to adopt more stringent standards in urban planning, as early as the late 60s in the 20th century, the early 70s had been specially made rubber for the base isolation, in some large buildings and bridges set on vibration isolation devices. These measures have made New Zealand in the early morning of September 4 occurred in the magnitude 7.1 earthquake, hit the
a statistics show that nearly 50 years, the same level of earthquake, the number of deaths in developing countries than in developed countries is 20 times more. New Zealand from the earthquake should learn from the lessons learned. In recent years, into the global seismic active period, frequency of extreme weather, earthquake science education becomes more important. The earthquake just happened in New Zealand became the most vivid teaching materials.
of the New Zealand government is concerned, they are often expensive and demanding for the implementation of standards has been criticized. The strict control of complicated, is bound to review the time-consuming, the cost increase.

New Zealand earthquake
New Zealand is a world leader in isolation technology level, research staff as early as the late 60s in the 20th century, the early 70s had been specially made rubber for the base isolation, in some large buildings and bridges, isolation and response set device, which will reduce the damage caused by the earthquake comes. This technology is also used in the Sichuan earthquake before. In addition,[link widoczny dla zalogowanych], residents of low-level and multi-use wood frame houses are basically a large glass of light construction, light weight, high strength, cost is not high, but also easy to be public acceptance.
New Zealand is located in the Pacific plate and the India - Australia's continental plates, is a circum-Pacific seismic belt. Wellington (Wellington) located on a fault runs through the area is clear, while the South Island's mountains, it is thousands of years by the collision of two plates made of. Christchurch University, Mark. Kui Keli (Mark Quigley), Professor of the causes of the earthquake, the two houses, they are completely torn in two earthquakes.
in this earthquake-prone countries, the annual number of earthquakes recorded 14000 times, residents can feel 150 times, an earthquake can cause damage to less than 10 times per year. However, there are several historical earthquake caused very heavy casualties and economic losses. 1931 occurred in the North Island Napier (Napier) in the Gulf magnitude 7.9 earthquake (Hawke's Bay earthquake) caused 256 deaths, the building was seriously damaged in the Gulf in a major earthquake destroyed almost exhausted, Napier City also was almost razed to the ground. Since then, New Zealand gradually learn and prevent tragedies from happening again. Therefore, causing the death of a recent earthquake dates back to 1968, leaving a total of three people were killed. Since then, the earthquake-prone countries has been maintained a zero death records.

U.S. Geological Survey said the epicenter was located 55 kilometers west of Christchurch, focal depth of 12 km. Anna lived in the neighborhood about 15 minutes from Christchurch city center by car, all the low wooden houses, and there is no large-scale damage. Anna standing after the earthquake before the house, surrounded by dark, car alarms chirping loud, resounding night. .
within 3 hours after the earthquake, occurred near the epicenter region is also 5 times more than magnitude 4.0 aftershock. Many residents simply have to sleep in his own direct car. Some residents are alarmed, have snapped up drinking water and food to the supermarket, went to the gas station to refuel. Supermarket quickly sold out of bottled water, food is also running low. Away from the epicenter of a dairyman close to Roger. Butters said:
Fortunately,[link widoczny dla zalogowanych], the earthquake caused no deaths, at present only two seriously injured, it is believed one of the 50-year-old man was injured by the fallen chimney, is still in intensive care, another man was shattered glass seriously stabbed. January of this year in Haiti, compared to the Richter 7.0 earthquake, the greater the strength of New Zealand earthquakes. Haiti 11.3 million deaths caused by the earthquake, New Zealand has created a
the popularization of knowledge of the people are very seriously. According to experts, based on past experience of the earthquake, 90% of the deaths were in ran out of the house staff after the house collapsed because of heavy objects falling down the wall to death. Also in the earthquake-prone Japan,[link widoczny dla zalogowanych], earthquake drills every year fixed, so when the earthquake comes, people will not panic disorder.
