蒙城台地磁“低点位移”异常特征及与华东及其临近地区地震关系初探
Geomagnetic Anomaly Characteristics of Mengcheng Station and Its Relationship with East China and Low Displacement Adjacent Area Earthquakes
【摘要】 本文分析了Z分量"低点位移"异常变化在地震前出现的异常特征、产生的背景、影响因素。得出了低点位移幅度大,频次高,异常可信度就高;异常幅度、震中远近及震级大小与异常间隔没有明显相关性;震中位置、震源深度与异常有着独特的关系的结论。
【Abstract】 This paper analyzes the weight of Z "low displacement" anomaly characteristics,background,and influencing factors before earthquakes.A conclusion is made that the credibility of the anomaly is high in cases of big-amplitude and high-frequency displacement;the anomaly amplitude,distance of the epicenter,the earthquake magnitude and anomaly intervals are of no significant correlations;location of the epicenter,depth and anomaly has a unique unusual relation.
