摘要
通过对陕西区域地下流体台网各井孔(泉)测项的观测数据进行跟踪分析,发现在较强地震发生时记录到了不同程度的远场同震响应。以2021年5月22日青海玛多7.4级、2022年1月8日青海门源6.9级两次地震为例,对陕西区域流体台网的水位和水温远场同震响应特征进行了分析,并对水位、水温发生远场同震变化的机理进行了初步的探讨。结果表明,水位的远场同震响应强于水温;震级越大,远场同震响应的测点越多,响应幅度也越大。
Based on the tracking analysis of the observation data of Wells(springs) in Shaanxi regional underground fluid network, it is found that different degrees of far-field co-seismic responses are recorded when strong earthquakes occur.In this paper, the co-seismic response characteristics of water level and water temperature in shaanxi regional fluid network are analyzed, and the mechanism of the co-seismic changes of water level and water temperature is preliminatively discussed, taking two earthquakes of M7.4 in Qinghai province on May 22,2021 and M6.9 in Qinghai Province on January 8,2022 as examples.The results show that the far-field co-seismic response of water level is stronger than that of water temperature.The larger the magnitude is, the more measuring points of far-field co-seismic response and the larger the response amplitude is.
