古地震学是适应重大工程建设中地震危险性评价的需要而发展起来的,它以鉴定和研究史前地震为主要内容。在与历史地震类似地质效应对比的基础上,古地震学研究已经提供了大量的不同构造环境下史前地震的证据,并已试图建立了多种断层习性模式。未来的研究重点应集中在检验和发展新的测年技术、系统调查历史地震事件以及阐述长期和短期的断层习性特征等方面。

Paleoseismology is a new subdiscipline in the earthscience field, developing for the need of earthquake-hazard assessments of major engineering and construction projects, whose principal extent is identification and study of prehistoric earthquakes. Based on analogy to the geologic effects associated with historic surface faulting earthquakes, paleoseismic studies have provided a vast amount of prehistoric earthquake evidences in different tectonic environments, and have attempted to establish various faulting earthquakes.Based on analogy of the geologic effects associated with

Key words: Paleoseismology, Earthquake-hazard assessment, Seismogenic fault, Fault behavior, Prehistoric earthquake
