长乐-诏安断裂带垂直形变与断层活动特征分析

ANALYSIS OF CHARACTERS OF VERTICAL DEFORMATION AND FAULT MOVEMENT OF CHANGLE-ZHAOAN FAULT ZONE

利用福建东南沿海7个跨断层短水准场地20多年的资料,分析了长乐-诏安断裂带的活动特征。结果表明:长乐-诏安断裂带全带活动性质基本相同,以压性逆断为主;断裂南段活动性强,北段活动性弱;沿海比内陆活动性强,总体呈现出从西北往东南、由内陆向海域逐渐增强的趋势。

The characters of movement cross-faults sites on the southeast coast of of Changle-Zhaoan fault zone were analysed by using levelling data of 7 Fujian over 20 years. It is shown that the deformation characters of Changle-Zhaoan fouh zone as a whole are generally the same. The movement of south segment is the greatest, and that of north segment takes second place. The coastal movement is greater than inland movement. Faults are generally pressure. The intensity shows to increase as the whole, from northwest to southeast, and from inland area to coastal area. The relation of fault movement and earthquake is also discussed.
