昔阳地震台水平摆倾斜仪和体应变仪经过多年的观测,积累了一定的地震异常变化资料。本文就2006年12月26日南海7.2级地震和日本8.0级地震前后两套观测仪器出现的异常变化和映震情况进行分析,特别是体应变仪的资料,观测稳定、精度高、可信度大,在不同震级、不同的距离、不同的方向都有震前异常反映。
Xiyang Seismic Station horizontal pendulum inclinometer and body strain gauge after years of observation, accumulated a certain amount of seismic anomalies changes. In this paper, the abnormal changes and the reflection of two sets of observational instruments before and after the MS 7.2 South China Sea earthquake and the MS 8.0 Japan Earthquake on December 26, 2006 are analyzed, especially the data of the body strain gauges, the observation is stable, the precision is high, the reliability Large, in different magnitudes, different distances, different directions have abnormal reflection before the earthquake.
