| 摘 要： | 五大连池火山爆发可分为两期、三个亚期。其中史前一期、两个亚期;有史以来一期、一个亚期。近半个世纪以来,该区地震频繁,且从微震至中强震,震源较浅,具有小震群、构造与岩浆活动等复杂震源机制的特点。初步分析,该区地震是其火山活动的组成部分。

| Abstract: | The volcanic eruption of the wudalianchi can be classified into two stages and three substages in which there were one stage and two substages in the prehistoric time, and one stage and one substage after the beginning of the recorded history. Since the last half century, there are frequent earthquakes with microseism to moderate-strong seism in this region. The focus of the seism is superficial, which has the characteristics of the complicated origin with small seismic cluster,structure, magmatic activity etc. According to the preliminary study, the earthquakes in this region resulted from the volcanic activities. |
