摘要
基于五大连池火山地质、地震活动和大地电磁深部探测资料,讨论了火山构造环境与地震活动的关系。受构造环境的制约,地震活动水平和空间分布特征与火山区断裂活动的强度与方式有直接的关系。老黑山附近东西侧地下介质的电性结构变化速度较大,与地震活动集中的事实相符,是现今火山区地壳浅层活动强的部位.
Based on the volcanic geology, seismicity and the data from etectromagnetic deep exploration in earth the relation between volcanic tectonic environment and seismicity is dis- cussed. In the light of tectonic environment restraint, horizontal and spatial distribution characteristics of the seismicity relate directly with strength and pattern of the fault activity in volcanic region. A more significant change of electricity structure of underground media both east and west side around the Iaoheishan mountain agrees with seismicity concentration and shows a strong part of shallow stratum activity in recent volcanic region.
