Abstract: Through the comprehensive analysis of hot spring distribution and its formation conditions, combined with regional geology, compared with the differences in the distribution of historical earthquake epicenter, the mechanism formation and tectonic background of hot spring were investigated in Changle-Nan'ao Faults Zone, SE China. the reason, differences distribution of hot spring, is the differences of tectonic-thermal, suggested different activity mode appeared in the same tectonic belt. A fault zone, developed hot springs, is active, but in different mode. The segment exposed hot springs(Fuzhou, Zhangzhou)creep, with more tectonic-thermal, but the part without hot spring(Quanzhou)stick-slip, with more devastating earthquake.
