长白山天池火山地震观测以来，记到了许多微小地震。对此，引起了许多专家们的关注。本文通过几年来观测到的资料分类和比较研究，对长白山天池火山地震波形特征进行详细的剖析，把长白山地震波形分成两大类，从第一类波形中找出反射波特征。这些活动特征表明，长白山天池火山可能属于活动火山，但现今处于相对稳定状态。 Since the observation of the Changbaishan Tianchi volcano, many minor earthquakes have been recorded. In this regard, aroused the concern of many experts. Based on the data classification and comparative studies observed over the past few years, this paper analyzes the waveform features of Changbaishan Tianchi volcano in detail and divides the Changbaishan seismic waveforms into two broad categories, and finds the reflected wave features from the first type of waveforms. The characteristics of these activities indicate that the Changbaishan Tianchi volcano may belong to the active volcano, but is now relatively stable.
