摘要

辽宁及邻区在2008～2010年发生了多次ML4.0级以上地震。笔者应用地磁加卸戴响应比方法对辽宁及邻区在2008～2010年地磁数字化资料进行处理。在考虑电离层扰动的基础上得出辽宁及邻区加卸载响应比方法P(Z)的高值异常与ML4.0级以上地震的对应关系,并总结得出辽宁及邻区P(Z)值映震异常的定量指标及异常变化特征与地震的关系。
Several earthquakes stronger than ML4.0 occurred in Liaoning and its adjacent region from 2008 to 2010.The author processed the digital geomagnetic data of Liaoning province and its adjacent region with loading and unloading response ratio.After eliminating the variation aroused from the ionosphere disturbance,the relationship between loading & unloading response ratio(P(z)) high value abnormities and earthquakes stronger than ML4.0 were revealed.The author also concluded the quantified index of the P(z)abnormities in Liaoning province,and the relationship between the abnormities and the earthquakes.
