| 摘 要： | 在跟踪分析肃南地震台2013—2017年洞体应变观测数据时发现,2017年6月20日NS分量曲线出现转折变化,23日到30日转折速率有所降低,调研该区地震活动性、自然条件、测区环境,并与同测点其他测项数据等进行对比,分析发现,该转折变化由观测山洞降雨渗漏引起,对渗漏点封堵后,该变化消失.

| Abstract: | When tracking and analyzing the cave strain observation data at Sunan Seismic Station from 2013 to 2017, it was found that the NS component curve turned back on June 20, 2017, and the turning rate decreased from June 23 to 30. The regional seismicity, natural conditions, and environment of the survey area were investigated and compared with other observation items at the same survey point. It is found that the turning change is caused by the rainfall leakage of the observation cave. The change disappears after the leakage point is blocked. |
