一、前言鲜水河断裂带是强震特别频繁、断层标志清晰、新构造运动强烈的一条大断裂带。现在,它已经成为国内关注的活断层之一。不过,它的研究工作的深度和广度还不及圣安德烈斯断层。为了深入研究该断层有关的一系列问题,本文把它与圣安德烈斯大断层进行对比,以期在研究中获得某些有益的启示,提出一些新的看法。 I. Preface The Xianshuihe fault zone is a large fault zone with strong frequent earthquakes, clear fault marks and intense new tectonic movement. It has now become one of the active faults of domestic concern. However, its research work is not as deep and wide as San Andreas Fault. In order to further study a series of problems related to the fault, this article compares it with the San Andreas fault so as to obtain some useful enlightenments in the research and put forward some new ideas.
