从图上可以看到湾区差不多近一般的地在liquefaction. 整个ALAMEDA/FOSTER CITY,半
个FREMONT/PA等等.
三谷地区PLEASANTON和DUBLIN有一大片地是liquefaction Zone, San Ramon要好很多.
liquefaction Zone能不能买?个人有个人的见解,我客人没看到因为liquefaction Zone
不抢房子的,更不用说卖不掉(没人买).
liquefaction Zone的房子相对来说地基出现沉降的可能性增大,但不是肯定地基有问题
. 三谷地区的平地比较多,即使地基有沉降,维修的费用也远比坡地修地基便宜很多.很
多沉降的房子几十后基本稳定了, 有的因为房子的排水不好,还继续沉降. 常见的方法
是修FRENCH DRAIN来疏导排水,房子水把地基下的土带走. 修沉降通常是把下降的地基
顶到水平位置,平地的LOT费用从2-3W到7-8W, 坡地很容易上十万.
总体上地基问题还是MONEY-FIXABLE的问题,只要价格合适,没问题. 而一些硬伤... 阅读全帖 |

当时那个3层小楼就像8楼贴的第一个图那样，楼体略略倾向地基那边歪着裂开的,现在想想当时从楼中跑出的惊慌失措的人群，还是有点后怕，当时人群说，在没有任何征兆的情况下，听到咔嚓几声巨响，眼看着自家的墙就裂了，好在当时是傍晚做饭的时间，大部分人都是醒着的，那个楼住的基本都是在downtown工作的年轻人跑的快。 |

这个report提供的是此房title是否Clean的信息。这个preliminary report的重要性不

和是否有各种lien的问题(例如mechanic lien, 就是原屋主曾经做过装修或扩建，却没
有付工头工钱，工头就会放一个lien在房子上，必须付清工钱之后，这房子才能再被买
卖）。preliminary report会使买家买房之后避免产权纠纷或者因为原屋主的欠款而损

发帖数: 4412 | 44 灾区地壳大幅位移 2011年3月1日 星期二 金羊网 -- 新快报
■地震造成基督城部分地面裂开。
据新华社电 日本国土地理院2月２７日说，他们分析日本“大地”号陆地观测技术
卫星发回的图像后发现，新西兰克赖斯特彻奇 地震灾区周边的地壳位移最大超过４０
厘米。
克赖斯特彻奇2月２２日发生的里氏６．３级地震出现如此大规模地壳位移是异乎
寻常的，国土地理院认为这主要是由于本次地震震源 较浅且当地地壳比较脆弱。
地壳位移幅度最大的地点在克赖斯特彻奇市区东南约５公里处，其地表向西南方向
偏移了约４０厘米，市中心也出现了十几厘米的位移，在周边地区还观测到了地震时液
化现象导致的地表变形。所谓液化现象是指处于地下水位以下的砂质地层在强震作用下
性质发生改变，表现出类似液体特征的现象。
国土地理院还确认，去年９月４日克赖斯特彻奇以西约４０公里处发生里氏７．１
级地震后，震源附近地表出现了水平方向最大４厘米的位移。国土地理院认为，去年地
震导致地壳变形产生的应力有可能逐渐传递到克赖斯特彻奇，最终引发了2月２２日的
地震。
