第一段Causesearthquakes occur when normal movements of the crust are concentrated into a single shock or a series of sudden shocks . aftershocks occur later as stresses are redistributed . The sequence is a follows. Rocks under stress..... Rocks deform.... Breaking point is reached.... Stored energy is released 第二段 Causesearthquakes occur when normal movements of the crust are concentrated into a single shock or a series of sudden shocks . aftershocks occur later as stresses are redistributed .

句子读起来要通顺才行
追答第一段 原因
地震发生在地壳的正常运动被集中到一个单一的震动或一系列的突然震动时。随后随着压力的重新分配,余震发生。顺序如下:岩石承受压力。。。岩石变形。。。超过临界点。。。储存的能量被释放
第二段
和第一段的英文发重复了,请检查
第三段 人类的影响
- 在南非Witwatersand地区,金矿的开采被认为改变了岩石压力,从而导致了频繁的地震活动。
- 水库原址本身并非地震构造,但在胡佛大坝和米德湖的建设之后,由于渗流,美国的内华达州和亚利桑那州在于1937年经历了超过100次的地震。
第一句话有点问题
这还有一点
Secondary factors: rain and strong winds increased landslide risk, Fires, broken glass. Broken water pipes. And lack of insurance meant that many lost their livelihood.
次要因素:雨和强风增加了山崩,火灾,打碎的玻璃,水管破裂的危险。安全不能保障意味着很多人将难以谋生。
第一句:导致地震发生 归因于地壳正常运动时一个单一的冲击或一系列的突然冲击。
最后一句话 与楼下同。
水库原址本身并非地震构造,由于渗流,美国的内华达州和亚利桑那州在胡佛大坝的建设和米德湖的建设后,于1937年经历了超过100次的地震。
