【摘要】 选取龙岩台的地磁资料,总结漳华龙地区震例,用压磁效应、感应磁效应等理论解释、分析地震与地磁异常的对应关系。结果表明,不同类型的地震,在孕育地震的不同时期,有不同的地质构造运动,产生的地磁异常也是不尽相同的。地磁异常的显著程度不仅与地震的应力降、震级、以及岩石的磁性有关,还和震源机制关系很大。更多还原

【Abstract】 Choosing the geomagnetic data in Longyan station and summaring the earthquake examples in Zhang-Hua-Long region as well as using the theoretic explain of piezomagnetic effect to analyze the corresponding relationship between earthquake and geomagnetic abnormity. The results show that different type of earthquakes during different seismogenic peoriod, have different geological structure movement and resulted geomagnetic abnormity also is different. The distinct extent of abnormity is not only associated with stress drop and magnitude as well as rock magnetism, but also focal mechanism largely.更多还原
