【Abstract】 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.更多还原
