| 摘 要： | 在对五大连池地震台１９８３年以来观测到的五大连池火山区的地震记录复核的基础上，测定了火山构造地震的空间分布状态。研究结果表明该地区地震活动均为壳内地震。受火山构造环境影响，地震活动存在着外围边缘强，震源深度分布深；内部弱，震源深度分布浅的差异。火山区内部地震深度分布优势在５ｋｍ—８ｋｍ，有３个地震分布密集区，震中分布呈明显的沿火山构造断层成带分布特性。在地震条带交汇处，震源深度起伏变化大，是火山构造活动强烈部位

| Abstract: | The distribution of tectonic earthquake in Wudalianchi volcanic area has been given on the basis of checking earthquake recorder since 1983.The result shows that all shocks in this area are belong to intracrust earthquake.Volcanic tectonic environment has influence on seismicity in the area.Seismic activity of the periphery of the volcanic area is more strong than interior.The focal depth of volcanic area is more shallow than outer,and depth distribution is from 5km to 8km.There exist three dense regions of epicenter.The epicenter distribution obviously show belt form along volcanic tectonic fault. |
