鲜水河断裂是我国著名的发震断裂,它与磨西断裂在康定地区交汇。磨西断裂呈NNW向展布,始于康定以北的中谷,终于石棉以南的公益海,与折多圹断裂在磨西交汇,与石棉断裂在安顺场交汇。温热泉沿鲜水河断裂带和磨西断裂带呈串珠状分布,前者多于后者。出露位置多在河流或沟谷谷底以及第四纪断陷盆地。热水集中分布区也是大震发生或中、 Xianshuihe fault is a well-known seismogenic fault in China, which meets the Muxi fault in the Kangding area. The Miesi fault was distributed in the NNW direction. It began in the middle valley north of Kangding. Finally, Gongyihai south of the asbestos intersected the Junduojie fault in Moxi and intersected the Asbestos fault in Anshun. Hot springs along the Xianshuihe fault zone and Muxi fault zone beaded distribution, the former more than the latter. Exposed more than in the valley or bottom valley and Quaternary fault basin.
