援引Newstalk 基督城2月22日大地震中死傷最嚴重的兩處——CTV和PGC大樓的地產危險性評估報告日前公布。
報告稱坎特伯雷電視台（CTV）及Pyne Gould Corporation公司建築物下的土壤被發現是非常易於“被搖撼”的，並且有很高的液化可能性。
由於這一土地狀況，這項報告或也適用於基督城其他的建築物。
CTV和PGC大樓的房產持有者稱在9月4日大地震後，該樓被定為可以進入，並且獲得了工程報告。
政府下令對受地震影響的建築物進行安全性調查。

不得不對Richmond的地基有所擔心,而且一旦有事十有八九會液化的,
所謂液化現象是指處於地下水位以下的砂質地層在強震作用下性質發生改變，表現出類似液體特征的現象。
路面一但液化,就跟這圖一樣:
根本開不了車,至少半米多深的泥水,廁所也沖不了水. -

Quake liquefaction damage in Christchurch huge: Japanese specialist

Some 49 square kilometers of land in quake-ravaged Christchurch, New Zealand, has undergone liquefaction -- a phenomenon that turns soil fluid in earthquakes -- a Japanese specialist says.
Susumu Yasuda, a member of the Japanese Geotechnical Society who is heading an investigation team in Christchurch following the Feb. 22 quake, said the city had been hit by one of the largest cases of liquefaction he had seen in over 30 years of conducting liquefaction surveys.
"Liquefaction, occurring mainly around the Avon River, is spread over an area of about 7 by 7 kilometers. Liquefaction flow, in which the ground moves horizontally, has also extended several meters, and buildings, bridges and sewer pipes have been damaged as a result. There have been few cases in the past in which damage from liquefaction has been so great," Yasuda told the Mainichi in a telephone interview.
Yasuda said that liquefaction flow resulted in building piles snapping and bridges being damaged. In many cases, large amounts of sand were pushed up out of the ground, with some areas seeing half a meter piled up.
Yasuda also visited Christchurch after a magnitude 7 earthquake hit the region in September 2010. He said that ground in the city was soft in areas where sand from the river had collected, making it easy for liquefaction to occur. In last year's earthquake, some 4,000 homes became uninhabitable. The damage is far greater this time.
"The amplitude of the latest earthquake was several times bigger than the one last year. The scope of liquefaction is also three to five times bigger, and there's a possibility the damage amount will get even greater," Yasuda said. -
