内蒙古阿拉善地区几次中等强度地震震源深度测定
Focal depth determination of several moderate earthquakes in Alxa region, Inner Mongolia Autonomous Region
摘要
Abstract
Focal depth is significant for seismogenic tectonic research.Earthquake activity is frequent in Inner Mongolia Alax area in recent years,with several moderate earthquakes occurred.In this article,we determined the focal depth of eight earthquakes,using PTD method,sPn-Pn method and CAP method.Results of the three methods were in accordance,with depth range of (18±7) km.关键词
