青藏高原东北边缘地震活动图像构造分析

THE STUDY ON SEISMICITY PATTERN ALONG NORTHEASTERN MARGIN OF QINGHAI-XIZANG PLATEAU

本文介绍了青藏高原东北边缘及其邻近地区的地震活动特征和地震线的展布，研究区共划分出８条主要地震线。在不同地震活动时期，各地震线上的地震活动水平不同。研究结果对于分析本区地震活动性和研究本区的地震预报是有益的。

This paper introduced the seismicity and distribution of seismic lines along the northeast-ern margin of Qinghai-Xizang plateau and in its adjacent regions.There are 8 main seismiclines in the studied area. During different seismic activity period,the seismicity level of eachseismic line is different.The results of study are advantageous to analyzing seismicity and fore-casting earthquake in this aera.
