摘要: 地震是描述地壳现今构造带和应力场的最佳信息源,包含了全面而又丰富的动力学内涵。根据全球地震的分布及其运动学、动力学特征,全球最活动的构造被划分为环太平洋构造系、大洋中脊构造系和大陆构造系等3个全球Ⅰ级构造系统。文中应用包含多种参数的哈佛CMT地震目录,研究了全球及其3个Ⅰ级构造系统的地震震源破裂类型、地震活动特征、震源深度分布特征等,讨论了三大构造系在这些方面存在的差别,进而说明了各个构造系在构造环境和动力作用方面的差别。

Abstract: Earthquake is the best information source for describing the present-day crustal tectonic zones and crustal stress field,containing comprehensive and abundant geodynamic connotations. Based on the distribution of global earthquakes and their kinematic and dynamic characteristics,the most active global-scale tectonics can be divided into three first-order tectonic systems:the circum-Pacific deep subduction tectonic system,the mid-oceanic ridge tectonic system,and the continent-continent shallow underthrusting tectonic system. This paper describes in detail the types of faulting of seismic source,the characteristics of seismicities and focal depth distribution in global scale and in the afore-mentioned three tectonic systems,by using the Harvard CMT catalogue,which provides various parameters of hypocenter. Furthermore,the differences of faulting types,seismicities,and distributions of focal depths in different tectonic systems are discussed as well. The results show that different tectonic systems posses different environment and geodynamical force.

Key words: Harvard CMT catalogue, global tectonic system, seismicity
