摘　　要：１９９７年６～９月在长白山天池火山区布设了数字化流动地震观测台网，对长白山火山地震活动进行了近震源观测，获取了大量与火山活动相关的地震信息。通过本次观测及资料处理，对长白山火山地震及其所反映出的应力状态有了一定的认识，为长白山火山活动研究提供了科学依据。rom June to September,1997,we had set up a portable digital seismic network on the summit of Changbaishan Tianchi volcano and in its vicinity for the near source observation of the volcanic seismicity and the stress condition under the volcano.A huge amount of seismic information relatied to volcanic activity of Changbaishan were obtained.By the observation and initial anlasis,we acquired a deeper understanding of the volcanic earthquakes and the stress condition that provides scientific basis for the activity of Changbaishan Tianchi volcano to be furtherly researched.
