【摘要】 本研究对云南漾濞6.4级地震后川滇地块及其周缘的地震活动性进行初步探讨,选取东经95°～110°和北纬20°～42°区域的M≥3.0地震,应用全国测震学科搭建的网络地震分析会商技术系统中"地震空区"扫描自动识别产出《地震空区扫描报告》(2021年6月6日),对研判川滇地块及其周缘地震活动的危险性和攀枝花地震监测中心站流体水温、流量观测数据变化进行了初步分析。根据研究结论推断川滇地块具有发生6.0级以上地震的背景。更多还原

【Abstract】 This study was focused on the preliminary analysis on the seismicity of the Sichuan-Yunnan Block and its surrounding regions after the Ms6.4 Yangbi earthquake in Yunnan.We selected earthquakes with M≥3.0 in the region of 95°～110°E and 20°～42°N latitude,and applied the " Seismic Gap Zone" from the established network for seismic analysis consultation technology system in National Seismological Survey to automatically produce the《Report of Seismic Gap Zone Scan》(June 6,2021),which helps to analyze and determine the risk of seismic activity in the Sichuan-Yunnan Block and its surrounding regions.Moreover,we analyzed the changes in the fluid temperature and flow observation data at the Panzhihua Earthquake Monitoring Center Station.Based on the abovementioned results,we suggested that the Sichuan-Yunnan Block shows the background of earthquake with magnitude greater than M6.0.更多还原
