摘要
本文对川滇地区1988年以来30次Ms≥5.0级地震前ML≥3.0级地震活动进行了分析。结果认为,中、强地震前ML≥3.0级地震活动的强度和频度曲线有一个非线性趋势增强的变化过程,曲线上升的非线性增强对整体区域一定时间段内有震、后续地震和无震的判断给出了震前地震活动的中、短期异常信息。
The seismicity with magnitude that is equal to or greater than 3.0 before an earthquake(Ms≥5.0)since 1988 occurred in Sichuan and Yunnan provinces is analyzed in this paper.Our study results show that before a medium-strong earthquake,a non-linear trending intensifying change process of the seismicity intensity and the frequency appears.And according to this increasing change process we guess an earthquake or a followed earthquake or no earthquake may occur in a period of time within a whole limited area.
