摘要:

对长白山天池火山监测站连续 4年的监测资料 ,包括测震 (含野外测震子台 )、形变 (含GPS和水准 )及水化等进行了认真的分析整理。同时将各手段所获资料与历年的资料进行了对比 ,对长白山天池火山目前的活动状态做出了初步判断。结果表明 :长白山天池火山目前正处于活跃状态 ,而且其活动性具逐年增强的趋势 ,主要表现为最近 1年来的火山地震频次和能量明显地增强

Abstract:

This paper presents the detailed analysis of various kinds of continuous observation data, including seismic records, deformation measurements (GPS and leveling measurements), and hydrochemical survey of groundwater obtained by the Changbaishan Tianchi volcano observatory in the past 4 years. At the same time, the comparative analyses between the obtained data with those obtained before have been carried out. Based on these data, the present state of the activity of Changbaishan Tianchi volcano is estimated
