利用加卸载响应比分析南昌地震台垂直摆倾斜仪观测数据
The analysis of observation data of vertical pendulum tiltmeter at Nanchang Seismic Station using loading/unloading response ratio
摘要
Abstract
The data of the vertical pendulum tiltmeter of Nanchang Seismic Station from 2008 to 2015 were analyzed by using the solid tide loading/unloading response ratio analysis method. It was found that the vertical pendulum observation curve had clear long trend and annual variation. It is found that the vertical pendulum observation curve has clear long trend and annual variation. Tidal unloading response ratio and earthquakes in and around the station earthquake obvious correspondence, showed significant deviation from the steady state value of 1, the abnormal thresholdY > 1.3, the error corresponding to a reasonable, with signiifcant high value anomalies before earthquakes. Between abnormal intervals, amplitudes and magnitude, epicenter distance, there are no significant proportion relationships, which may related to the complex dynamic processes of different earthquakes.关键词
