摘要
在近2年的前兆观测实践中，我们发现了一种十分有趣的、奇特的现象：在1996年3月19日新疆阿图什6．9级强震发生前和1997年3～4月新疆伽师6级强震群发生前，在远隔2500公里外的四川地区观测到了多种前兆手段的群体突变事件。我们称它为强震的“远场效应”。本文还对它的成因机制作了初步的探讨。
In recent two years, an interesting phenomenon was found in our premonitory observation of earthquake. Before both March 19, 1996 Atushi M6. 9 Earthquake and March to April, 1997 Jiashi Swarm of Earthquakes (main shock M=6), many kinds of earthquake premonitory obser vation data show a group sudden changes in Sichuan area. We call these phenomena premonitory far-field effect of strong earthquake and give out our explanations.
