If a fault has a vertical fault plane. How do we determine its hanging wall and footwall?

若一断层的断层面是直立的，我们怎么去确定它的上盘和下盘呢？

If the relative movement of hanging wall and footwall is parallel to the strike of fault plane, it is a strike slip fault.

如果断层上盘和下盘的岩石相对位移运动是平行断层面走向的，这种断层称为走滑断层。

Then the block in the southern side of this fault is the hanging wall and the block in the northern side of this fault is the foot wall .

那么，位于这条断层南侧的岩层是上盘，位于这条断层北侧的岩层则是下盘。

For example, a normal fault is one which the hanging wall moves directly down the dip relative to the footwall and a reverse fault is one which the hanging wall goes directly up relative to the footwall.

例如，上盘岩石相对于下盘岩石向断面倾向下滑的断层命名为正断层，逆断层的上盘岩石相对于下盘岩石沿断面向上直冲。

The Taichung Domain was moving northwestwards before the 1999 Chi-Chi earthquake: in the footwall of Chelungpu Fault the slip rate was ~10 mm/yr, while in the hanging wall the rate increased eastwards up to 10-30 mm/yr. Two years prior to the earthquake, in the footwall of Changhua Fault the deformation direction changed from WNW to almost due N, and velocity gradient changed from increasing northwards to increasing eastwards, suggesting possible precursor of a large earthquake.

中部地区在集集地震前大致向西北方向位移，车笼埔断层下盘位移速率约在10 mm/yr左右，断层上盘往东侧逐渐增大，在10~30 mm/yr之间；集集地震发生前2年，彰化断层下盘的位移方向由西北西转为偏北的位移型态，位移速度则由南向北增大，转为由西向东增大的趋势；即位移方向与位移速度有明显的改变，可能为地震前兆的相关资讯。

As for coseismic deformation of Chi-Chi earthquake, the footwall of Chelungpu Fault moved southeastwards 0.3-1.5 m, and the value was increasing toward the fault; the hanging wall moved northwestwards 1.4-7.0 m, but the value was smaller south of the Choshui River. After the Chi-Chi earthquake, the hanging wall of Chelungpu Fault was still moving west-northwestwards and kept uplifting, while the footwall gradually changed direction from ESE to WSW or even WNW, clockwise resuming to inter-seismic deformation pattern. It is interesting to notice that despite the largest coseismic deformation in the northernmost segment of Chelungpu Fault, the post-seismic deformation peaked around the epicenter of Chi-Chi earthquake.

集集地震之同震变形，在车笼埔断层下盘向东南方向位移0.30~1.5 m，且越靠近断层位移量越大；车笼埔断层上盘则向西北方向大幅位移约1.4~7.0 m，浊水溪以南的位移量较小；集集地震以后之震后变形型态，以车笼埔断层为分界，上盘在震后向西北西方向位移的型态仍与同震时相同，下盘由同震时一致性的向东南东方向，逐步向西北西或西南西方向位移，亦即在车笼埔断层下盘有逐步依顺时针方向回归至震间的滑移型态；另就位移速率而言，虽然同震变形最大地区在车笼埔断层北端，但其震后的变形量最大地区，却集中於震央位置附近；就地震循环而言，震后的6年期间仍处於地层压密重整阶段，尚未回归至该区震间阶段的位移状态。

The results show that the condition and the stability on the bottom of slope is bettero As a whole, the angle of slope is likely to increase and turn to craggedness ; The condition and the stability on the top ...

结果表明：采场下盘边坡岩性条件较好，稳定性较高，总体边坡角均有可能进行加大、加陡：上盘边坡岩性条件相对较差，且地下水位较高，边坡的稳定性相对下盘较差。

With the compressional stress increasing,the dip-slip motion in listric fault system could successively generate reverse-"fish-fork-shaped" structure,hanging wall interpenetration thrust,footwall shortcut thrust,"backward broken" footwall shortcut thrust imbricated fan,"backward broken interpenetration" thrust,.

From the upper part of the ore body to the rear part, [w(Na2O×w]/[w(K2O)×w] decreases regularly. The element association in the hanging wall is obviously different from that in the lying wall: the hanging wall is enriched with siderophile elements, while the lying wall has abundant thiophile elements.

多元素累乘比值[w(Na2O)×w]/[w(K2O)×w]从矿上向尾部具有规律的下降，矿体上、下盘的元素组合明显不同，矿体上盘富集亲铁元素，矿体下盘富集亲硫元素。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
