On the whole , the main shock ruptured from the east to the west 总体上说，主震是由东向西破裂的。

This insight corroborates the idea that a major shock relieves stress ? and thus the likelihood of a second major tremor ? in some areas 这个洞见证实了一种概念：在某些地区，主震会释放应力，因此有第二主震发生的可能性。
3.
The aftershocks were distributed on ( or near ) the fault plane and were triggered by the stress redistribution in the medium in the nearby region of the fault plane 余震发生在主震的断层面上(或其附近) ，是由主震断层面附近介质的应力调整造成的。

More locally , the earthquake and its aftershocks changed the shape and orientation of virtually the entire burma plate and the lands it supports ? in particular , the andaman and nicobar islands 最剧烈的改变发生在震央附近更为局部的区域：主震和馀震几乎完全改变了缅甸板块及其上方岛屿的形状和方位，尤其是印度的安达曼和尼古巴群岛。

A chain of continuous tremors followed the main quake . on september 29 , an aftershock with a magnitude of 6 . 8 again hit central formosa , causing severe damage to the area . to date , the death toll totals more than two thousand 在主震过后馀震不断， 9月29日一场规模6 . 8级的馀震再袭福尔摩沙中部，再度在中部地区造成严重的损害，截至目前为止，共有两千多人死亡。

The strike - slip faulting was caused by asymmetrical distribution of barriers on the subducting plate . the nne - ssw distributed aftershocks occurred on , or near , the fault plane of the main shock ; while the nw - se distributed aftershocks , on , or near , the mentawai fault 北北东?南南西向分布的余震发生在主震的断层面上(或其附近) ；而西北?东南向分布的余震则发生在明打威断层上(或其附近) 。

Several important conclusions are gained by the analysis of push - over method and quasi - static reversal load pattern to a reinforced concrete structure : under the two earthquakes , the responses of structure are more serious than the responses under single earthquake , by the conclusion , it is not rationality that structure ' s earthquake damage prediction under single earthquake ; the main - after earthquake action is different from fore - main earthquake action under the same earthquake magnitude combination ; the push - over analysis to the structure is convenient and utility , it also reflects the response and performance of structure under the earthquake , so the method ' s development future is wide . based on the research of the former scholars , some means of structure resisting earthquake are introduced in the last part of this thesis , and the result of earthquake damage prediction for the planning area of quanzhou city is given 通过对一钢筋混凝土结构进行push - over分析与拟静力循环往复加载分析，得到了一些重要结论：在两次地震动作用下，结构物的反应比仅考虑一次地震动作用时的反应要严重的多，从而说明传统上仅仅考虑一次地震动作用的建筑物震害预测是不合理的：即使在同震级组合的两次地震作用下，前震主震型、主震余震型地震对结构物产生的破坏作用也是不尽相同的；对结构物进行静力弹塑性分析的方法( push - over方法)简便实用，并能较准确地反映大震下结构的一般性能和反应，再一次的证明了该方法具有广阔的发展前景；根据前人的研究成果，在本文的最后，简单的介绍了一些结构物抵御多次地震破坏作用的方法，并给出了泉州市规划区内钢筋混凝土框架结构群体震害预测的结果。

The sequence and activity characteristics of shuikou reservoir induced earthquake are analyzed with several methods , such as probabilistic evaluation , comprehensive effect parameter e evaluation , two - step comprehensive fuzzy evaluation , the maximum magnitude of historical earthquakes evaluation , etc . . the results show that the shuikou m ( subscript l ) 4 . 1 earthquake on april 21 , 1996 is a main - earthquake , and from now on , the possibility occuring m ( subscript l ) > 3 induced earthquake in shuikou reservoir area is low 摘要应用概率法、综合影响参数预测法、两级模糊评判法、古登堡里克特公式外推预测法等对水口水库诱发地震序列以及活动特征进行了研究，认为： 1996年4月21日发生的m (下标l ) 4 . 1地震为水口水库诱发地震主震，今后库区发生大于3级以上诱发地震的可能性较小。

“ the fact is that many main shocks do not occur " suddenly " : 10 - 30 % of them are preceded by foreshocks during the week before their occurrence ; some are preceded by year - long pre - activity9 ; some are preceded by increased moment release during the years before them10 - 14 , and some are preceded by seismic quiescence15 - 17 “事实是，许多主震并非‘突然’发生主震中的10 - 30 %之前在发震之前的一周有前震；有的主震前有长达一年的震前活动性34 ；有的在震前有数年的加大的瞬间释放3536373839 ，有的则在震前出现地震活动性的静止404142 。
