摘要

本文介绍了1979年3月15日普洱6.8级地震当天,在距离微观震中仅6.4km的磨黑镇,现场安装的陶瓷偏角磁变仪的磁系出现了异常大幅度摆动的事件,笔者从陶瓷偏角磁变仪的观测原理和地震当日的地磁场活动程度等方面,分析了造成这次异常事件的原因,并指出这种异常现象可能与地震前的震磁效应有关。
Unusual swing of the magnet of Chinaware Magnetic Declination Variometer (CMDV) was observed before the Puer Earthquake (MS=6.8) in 1979. The instruments being used are installed at Mohei Town which is only 6.4km away from the epicenter of Puer Earthquake. The principle of CMDV and the magnetic activity background level are introduced in this paper, and the unusual swing magnetic signal is believed to be the result possibly caused by the earthquake.
