摘要
通过对云南近 50 0年来 ,特别是 2 0世纪以来地震灾害记录的系统分析 ,揭示了云南震灾的基本特征 :(1)震灾具有空间差异性 ,红河断裂以东地区的震灾重于以西地区 ;(2 )震灾随着强震平静期、活跃期的交替而表现得轻重不一 ;(3)震灾因社会经济的快速发展而日趋严重。这些特征的形成 。
Through analysing seismic disaster data in Yunnan in the past 500 years, especially in 20th century, we think there are following basic seismic disaster features in the area: (1) the seismic disasters are different in spatial distribution, heavier in the east of Honghe Fault than in the west; (2) the degree of disasters changed with quiet and active earthquake periods alternatively; (3) disasters are becoming serious with the rapid development of society and economy. We thought the forming of features is related to Yunnan's geological tectonic environment, social economic conditions and human culture features.
