西安市地下热水开采对地震活动的影响
|
摘要
利用西安地区的地下热水资料和陕西省地震台网的地震观测资料,研究了西安地区地下热水开采和地震活动的关系。结果表明:西安地区地下热水的开采造成此区域地震震中分布趋向于集中在长安—临潼断裂的两端,而地下热水开采区—西安城郊区的地震则明显减少。
Based on data of thermal groundwater and earthquake records of the seismic network of Shaanxi Province,the relationship between the exploitation of thermal groundwater and seismic activity in Xi'an region is studied in this paper.The results show that with the exploitation of the thermal groundwater,the distribution of earthquake epicenter in this region transfers to the two ends of the Chang'an—Lintong fault,but in the urban and suburb of Xi'an,where thermal groundwater is mined,the number of earthquakes reduce obviously.
