| 摘 要： | 本文用地震活动性参数等地震学方法和用时间域小地震地震图测量震源物理参数及介质Ｑ值等震源参数方法，对伊通－舒兰断裂进行分段及地震危险性探讨。初步研究结果表明该断裂乌拉街－舒兰段（北段）、伊通－双阳段（南段）存在明显差异，北段介质强度大，易积累能量而发生较大地震。

| Abstract: | In this paper,Shulan-Yitong fault is segmented and its earthquake risk is dis-cussed by seismological methods,such as parameters of earthquake activity,focus parame-ters,and Q value of medium, by means of seismic record of small earthquakes in time do-main.The results of preliminary study have shown the difference between the sourth segment(Yitong-Shuangyang)and the north segment(Wulajie-Shulan)in which medium strength ishigher.Accumulating energy is easier this will lead to larger earthquake in the north seg-ment. |
