摘要
白头山火山地震分为四种类型,其地震特点是频度高、强度低震源集中。活动强度在时间分布上具有明显的规律性,虽然白头山火山活动目前处于平静状态,仍应注意监视。
The seismic activities of the volcanic earthquake in Baitou Mountain area can be divided into four types. These volcanic shocks are possessed of characteristics of high frequency,lower magnitude and concentrated seismic focus. Regularity of earthquake sequence in time is obvious. At present the volcanism of Baitou Mountain is in quiet state,but still should be monitored closely.
