Yun Zhou · Journal of Disaster Prevention and Mitigation Engineering · 2008
A M6.4 earthquake occurred in Pu′er of Yunnan province on Jun.3,2007,the focal point of which was at a depth of only 5 km. Due to the impact of the earthquake,most of local buildings and structures suffered damage to varying degrees. Based on the field investigation,the intensity distribution and destruction grade in disaster area were introduced,the seismic damage of construction were investigated,which usually contained earth-timber structure,brick-timber structure,brick-concrete structure and frame structure. Meanwhile,failure of critical infrastructure such as water supply and drainage system,transportation system,electric power system,communication system and hydraulic engineering were also summarized,and the possible causes of various damages to construction and infrastructure were analyzed in terms of different categories. Finally,the characteristics of the damage in this event were concluded,several suggestions for future earthquake prevention and disaster mitigation in village and town were made in this paper.
