| 摘要: |
| 基于全国地震地下流体台网数据库,分析了2022年1月8日青海海北藏族自治州门源县 MS6.9地震引起的地下流体井水位、水温同震响应特征。结果表明:本次地震引起的水位同震响应观测井数量远大于水温;水位同震响应开始时间、结束时间均优先于水温,水温同震响应是水位同震响应的次生变化。对比门源2022年1月8日 MS6.9和2016年1月21日 MS6.4地震,发现地震能量不同是造成两次地震同震响应差异的主要原因。 |

| Abstract: |
| Based on the database from underground fluid national network,this paper analyzes the coseismic response changes of underground fluid water level and water temperature caused by the MS6.9 earthquake in Menyuan. The results show that the number of coseismic responses of water level is much larger than that of water temperature. The start and end time of the coseismic response of the water level is prior to the water temperature. The coseismic response of water temperature is the secondary change of the coseismic response of water level. Finally,by comparing the two earthquakes in Menyuan,it is found that the seismic energy is the main reason for the difference in the coseismic response of the two earthquakes. |
