摘要:
对云南云县地震台洞体应变和水管倾斜观测值与降水量的对比分析,结果表明,云县年降水总量每增加200 mm,洞体应变和水管倾斜的增量分别约为4 000×10-8和90″; 月降水增加100 mm,云县洞体应变和水管倾斜月变幅的增量分别约为38×10-8和2.5″。构建月降水和月增量的线性方程,求取测值与理论值的残差,发现当残差量大于1倍均方差后,短期内台站周边500 km范围内均有5.5级以上地震发生。距离台站最近的昌宁5.1级地震前,异常幅度最大,表明排除降水干扰后的变形增大,多与构造活动有关。
Abstract:
In this article,through comparative analysis on the cavity strain and inclined pipe observation value and precipitation in Yunxian seismic station,we found that there have a certain correlation between each other.Quantitative analysis result shows,the total annual precipitation increased by 200 mm,the influence on the cavity strain is 4 000×10-8 and the influence on the inclined pipe observation value is 90″; The monthly precipitation increased 100 mm,the cavity strain and inclination observation value increase monthly in amplitude,are respectively 38×10-8 and 2.5″. After constructing the linear equation of monthly precipitation and monthly increment,the residual of measured value and theoretical value are obtained.When the residual quantity is 1 times more than the mean square deviation,there are M≥5.5 earthquakes occurred in the vicinity of 500 km from station in the short term.The nearest distance station from Changning MS5.1 earthquakes shows the maximum amplitude of anomaly,which shows that the deformation increases after the precipitation disturbance,and are related to the tectonic activity.
