罗云山断裂带形变异常强度与地震关系的研究

Study on the Relationship between Earthquakes and Deformation Anomaly Intensities of Mount Luoyun Fault

对临汾中心地震台跨断层短水准观测资料进行整理,根据断层形变观测资料计算历年的断层垂直变化速率,并以平均速率为基值,用不同时间的速率与平均速率值之比,根据数学模型解算出断层形变异常强度值R,根据计算结果绘制了异常强度时序曲线图,根据变化特征研究其与山西地区近年来ML≥4.0地震的关系,进一步探讨山西地区异常强度随时间的变化情况,为未来震情形势的预判提供证据。

The observation data of the short-range leveling across faults at Linfen Central Seismological Station are made in order in this paper.According to these observation data,each year＇s vertical deformation velocity of the Mount Luoyun fault is calculated.Taking the average velocity as the base value and using the ratios of velocities in different time over the average,the deformation anomaly intensity R of the fault is calculated based on a mathematical model.According the results,the time sequence of anomaly intensity is figured out.In addition,the relationship between variation characteristics and the ML≥4.0 earthquakes in Shanxi region in recent years is studied,and the variation of anomaly intensity with time is further discussed,which may provide evidence for earthquake prediction in the future.
