中文摘要:

在 Jingpohu 暴烈的区域的 Seismicity 基于由在坑福雷斯特附近与24位宽带 3- 部件地震计装备的 14 个车站组成的活动地震网络记录的地震数据被调查。结果证明显得肯定在有低活动水平和大多数记录地震的 Jingpohu 和它的邻近的区域的 seismicity 是暴烈构造的。地点的结果显示 10km 的主导的焦点的深度 - 30km,大多数地震比 ML 小 > 2.0,并且在“坑福雷斯特”并且在跑过暴烈的区域的 Dunhua-Mishan 差错上的区域被集中。在车站 No.2,它有更好的观察条件,事件的二种类型,多半联系了到火山作用,被记录;他们的波形特征有点类似于长时期的暴烈的事件和暴烈的震颤的,但是与频率的不同特征。

英文摘要:

Seismicity in the Jingpohu volcanic area was investigated based on the seismic data recorded by the mobile seismic network consisting of 14 stations equipped with 24-bit broad-band 3- component seismographs around Crater Forest, Results show that there appears certain seismicity in Jingpohu and its adjacent areas with a low activity level and most of the recorded earthquakes are the volcanic-tectonic ones, The results of location indicate a dominant focal depth of 10km - 30kin, most of the earthquakes are smaller than ML2,0, and are concentrated in the area of " Crater Forest" and on the Dunhua-Mishan fault which runs through the volcanic area. At station No. 2, which has better observation conditions, two types of events, likely associated to volcanism, were recorded; their waveform characteristics are somewhat similar to that of the long-period volcanic event and the volcanic tremor, but with different feature of frequencies.
