水库触发地震研究进展

水库诱发的地震活动由于其潜在的破坏性巨大而受到重视。自1945年Carder首次指出美国米德湖水库蓄水触发地震后,各国学者针对不同地区的水库触发地震进行了大量研究。本文总结前人研究的结果,将人类对水库触发地震的研究内容从以下四个方面进行了归纳:(1)空间分布;(2)触发机理;(3)类型;(4)特征。并提出了今后研究的重点和方向。通过水库触发地震研究综述,为我国进一步开展地震活动与水库运行之间关系的研究提供了科学依据。

ADVANCES IN RESERVOIR-TRIGGERED SEISMICITY

Reservoir-triggered seismicity(RTS), namely earthquakes induced by filling of artificial water reservoirs , is known for its potential large devastation to people in the vicinity of the reservoir, and today it has been globally identified. Since the Triggering of earthquakes by artificial water reservoirs was for the first time pointed out by Carder (1945) at Lake Mead in the United States of America, the RTS has been studied globally. Based on addressed papers, the present review summarized the achievements on RTS as four aspects followed: (1) the spatial distribution; (2) the triggering mechanism of earthquake by reservoir; (3)its types and (4) its characteristics. Then this paper put forward and discussed some further researching contents in the RTS. This paper provides important referent worthiness for more researching on RTS in the future.
