Abstract: An earthquake of magnitude 5.5 had taken place in Xunwn, Jiangxi Province, on August 2, 1987. Its epicenter is located at 24? 58′N. 115?39′E and focal depth is 13km. The earthquake-generating structure and its rupture pattern by the shock are analyzed from the characteristics of earthquake hazards, data on activites of crustal structures, focal mechanism, preferred orientation of the damaged structures and the conditions of medium in this paper.

Key words: Earthquake hazards, Jiangxi, Xunwu earthquake, Rupture pattern
