云南地震监测台网进展与强震活动特征分析
|
摘要
介绍了云南地震监测台网的发展历程。云南区域数字地震台网的运行,极大地提升了地震活动的监测能力,小震活动信息量成倍增加。近年来全球及区域数字地震台网的运行,记录了许多重要的地震事件,为现代地震学领域的理论创新和技术应用研究提供了广阔的前景。长期以来积累了大量高质量的数字地震观测资料,是地震学家和相关领域的地球科学家深入开展地震物理过程和地球内部结构研究的重要基础资料。重点分析了20世纪以来云南M≥5.0地震活动性在时间和空间分布上所表现出的基本特征,这些特征对分析研究云南地震活动以及强震危险性具有重要参考价值。
Firstly,we introduce the development process of Yunnan Seismic Monitoring Network(YSMN).The running of Yunnan Regional Digital Seismic Network improves the monitoring ability of seismic activity,so we collect the double information of small earthquakes activities.In recent years,lots of important earthquake events are made to record by the running of digital seismic network in region and global,which provide a good future for the theoretical innovation and research on technology application in modern seismology.Accumulating massive observation data with high quality for a long time is the basis of studying the physical process of earthquake and internal earth structure.Finally,we analyze the time and spatial distribution characteristic of Yunnan M≥5.0 earthquakes activities since 20th century,and it is the important reference on analyzing the earthquake activity and strong earthquake risk in Yunnan.
