云南省地震活动与雷电活动时空对比分析

The time-space comparison analysis of seismic activity and thunder lightning activity of Yunnan

该文利用2011—2015年云南省地闪资料及1900—2013年云南省地震活动资料,通过对雷电活动的年分布、月分布、日分布以及密度空间分布和雷电活动强度分布的分析,与地震活动的时间分布、空间分布进行对比。利用Arc GIS软件作出1900—2013年全省地震与年平均地闪密度、正负闪强度叠加图和6级以上强震与年平均地闪密度、正负闪强度叠加图,找出地震活动高发区的雷电活动分布规律,为防灾减灾工作提供理论依据。

This article applied the datum of CG lightning of Yunnan during 2011 to 2015 and seismic activities of Yunnan during 1900 to 2013. Analyzed the thunder and lightning activities of years, months and days distribution,density distribution in space and intensity distribution then made a comparison with the seismic activities of time distribution and spatial distribution. With the help of ArcGIS software, made the stacking chart of the whole province earthquake during 1900 to 2013 ,annual average lightning density and positive and negative lightning intensity, and another stacking chart of magnitude 6.0 or over earthquake , annual average lightning density and positive and negative lightning intensity. Finding the distribution regularities of thunder and lightning in frequent earthquake area so as to provide theoretical foundations on disaster prevention and mitigation.
