【摘要】 平安电磁波东西向数据在2008年汶川8.0级地震、2010年玉树7.1级地震前都有明显的高脉冲反应,因此统计了1993年平安电磁波仪器架设以来的观测数据变化与地震的对应情况。根据震级和震中距的约束条件选取了12次6级以上地震,发现其中在8次强震前有明显的异常现象,说明该测项在青藏块体北部地区6级以上地震前有较好的异常显示。更多还原

【Abstract】 There have clear high pulse response signal data recorded by Ping’an electromagnetic wave station before Wenchuan Ms 8.0 in 2008 and Yushu Ms 7.1 in 2010.For this reason,the authors have analyzed statistically the data since 1993,and according to the constraints of magnitude and epicenter distance,they have select 12 earthquakes with Ms≥6.0,and found that data were remarkably abnormal before 8 strong earthquakes.The result shows that the electromagnetic data have a good indication in short-term earthquake prediction in north of Qinghai-Xizang plateau.更多还原
