摘要
1996年11月17日至29日在新疆喀什地区发生8次地震,震前均观测到地磁脉动异常.文中对未发生地震期间地磁脉动观测的背景环境以及喀什台常见的地磁脉动进行分析,然后对地震前地磁脉动异常现象进行研究,并初步探讨这种震前地磁脉动异常的产生机制.这种震前发生的地磁脉动异常在地震的短期预报上可能有广泛的应用前景.
Abnormality of geomagnetic pulsations was observed at Kashi region in Xinjiang before each of 8 earthquakes taking place from Nov. 17 to 29 in 1996. In this paper observation background and normal pulsations without earthquake are analyzed,abnormality of geomagnetic pulsations before earthquake is studied, and generation mechanism of the abnormality is discussed. This kind of pulsation abnormality before earthquake can be used in short bine prediction.
