西安地区地下热水季节性活动与区域地震活动的关系研究
|
摘要
根据西影井热水水位的观测资料,分析了西安地区地下热水活动的季节性特征及其与区域地震活动的相关性。结果表明西安地区地下热水活动与区域地震活动明显相关,其相关性基本不受季节性用水的影响,反映出它们受同一构造力源的控制,同时,西安地区地下热水活动与西安及邻区的地震活动最为密切。
Based on the geothermal water level data of Xiying well and the earthquake data recorded by the seismic network of Shaanxi province,the relationship between the seasonal activity of geothermal water and regional seismic activity is studied.The results show that the activity of geothermal water in Xi'an is obviously related to the regional seismic activity,and the correlation is not influenced by the seasonal exploitation of underground water,which indicating they are both controlled by the same tectonic source force.And the activity of geothermal water has the closest relationship with the seismic activity in Xi'an and its neighboring area.
