Abstract: Yunnan province is a region of frequent earthquake disasters,with lightning easily leading to mass disaster events.Taking Zhaotong M6.5 earthquake stricken areas as an example and combining nearly 30 years of thunderstorm days statistics,lightning monitoring data during 2009—2013 and lightning disaster data during 2006—2015,on the basis of analyzing the characteristics of lightning activity,we have established the occurrence pattern of the disaster stricken areas as to lightning potential vulnerability evaluation index,the lightning disaster vulnerability evaluation index R and lightning disaster vulnerability zoning map.The results show that Qiaojia county is a high vulnerability area,and Ludian County for lightning disaster vulnerability area.Lightning activity has presented obvious seasonal variation,with frequent lightning occurrence and strength density.Lightning activity from the afternoon can gradually increase.Therefore vulnerability analysis assessment and zoning of thunderstorm can provide necessary reference to determine the focus of lightning protection and to guide the reconstruction site selection and construction.Different regions should adopt corresponding lightning protection measures according to the lightning disaster risk level.
