ABNORMAL STUDY ON IMPENDING TYPICAL FLUCTUATIONS OF
LINFEN HORIZONTAL PENDULUM
1）Linfen Central Seismostation of Earthquake Administration of Shanxi Province，Linfen 041000
2）Institute of Seismology, CEA, Wuhan 430071
3）National Continental Rift Valley Dynamics Observatory of Taiyuan,Taiyuan 030002
Abstract：The typical distortion phenomenon of earth tidal curve from horizontal pendulum at Linfen seismostation before the earthquakes is analyzed, the probability of typical fluctuation appearance before the earthquakes is calculated in both space and time, the physical mechanism of the typical abnormal events is explained.The analysis results can be a preliminary judgement condition of earthquake.
