摘　　要：对苍山5．2级地震前后鲁南流动地磁观测网地磁场总强度的变化进行了分析、研究，认为该区地磁场总强度的异常是苍山5．2级地震的前兆反映，而且震中正处于地磁场变异带附近。The variations of geomagnetic field total intensity of Lunan mobile geomagnetic observation network before and after the Cangshan M 5. 2 earthquake have been analyzed and studied. It is considered that the anomaly of the geomagnetic field total intensity of this region was the resPOnse of the Cangshan M 5. 2 earthquake, the epicenter is right located near the anomalous zone of the geomagnetic field.Subjectwords: geomagnetic anomalyl Shandong ; seismic precursor

关 键 词：地磁异常 地震前兆 地磁场 地震
