长白山天池火山地震记录波形分析

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。

Waveform analysis of earthquakes in Tianchi volcano region, Changbaishan

A lot of microearthquakes have been observed during the last decade in the Tianchi volcano region, Changbai Shan, which arouses wide interests among scientists. This study analyses the recorded seismic wavedforms of these earthquakes in detail by making classification and comparison. The waveforms are classified into two categories, with the first category displaying reflected phase. The observations and analyzed results indicate that the Tianchi volcano may be active, but now is in a relatively stable state.
