【摘要】 1996年11月17日至11月29日在新疆喀什地区8次地震期间观测到的震前发生的高频地磁脉动现象．文中对每次地震前的Pcl-2脉动的形态，以及脉动的起始时刻、持续时间、H分量和D分量的平均振幅随北京地方时的分布进行了详细研究分析．对这种震前观测到的高频地磁脉动的激发机制也做了深入的讨论．事实表明，这种震前发生的高频地磁脉动在地震的短期预报上可能有广泛的应用前景．更多还原

【Abstract】 Abnormality of geomagnetic pulsations was observed at Kashi region in Xingjang before each of 8 earthquakes took place from Nov.17 to 29 in 1996. In this paper the morphology, begin bine, duration, H and D average amplitude of each geomagnetic pulsation during earthquakes are analyzed in detail. And generation mechanism of observed special pulsations is discussed. In fact this kind of pulsation abnormality before earthquake can be widely used in short time prediction.更多还原
