摘要
利用现有高精度流动重力测网观测资料,总结2016-10-20江苏射阳4.4级、2017-06-16湖北秭归4.3级、2017-07-15广西南丹4.0级、2018-02-09河南淅川4.3级等4次地震相关重力变化,探讨利用流动重力观测手段监测弱地震活动背景地区地震活动的可行性,并给出相应建议。
Based on the high accuracy observation data from the mobile gravimetry network,the gravity changes of four earthquakes,including Sheyang M4.4 earthquake on October 20,2016 in Jiangsu,Zigui M4.3 earthquake on June 16,2017 in Hubei,Nandan M4.0 earthquake on July 15,2017 in Guangxi,and Xichuan M4.3 earthquake on February 9,2018 in Henan,are summarized.The feasibility of small earthquake monitoring by mobile gravimetry in areas of weak seismic activity background is discussed,and some corresponding advice is given.
