中国大陆地震构造研究回顾

Review on Study of Seismotectonics in China

  • 摘要: 简要回顾了近4年来(1999~2002年)我国在地震构造方面研究的进展,重点介绍了在地壳上地幔结构、活动断裂和大地震构造背景、地壳形变和数值模拟方面的工作.在我国境内发生的绝大多数地震都属于大陆地震的范畴,因此,中国地震学家把研究的重点放在大陆地震上.中国在九五期间完成的中国数字地震观测系统和中国地壳运动观测网络重大科学工程为地震构造的研究提供了大量的基础资料.因此,4年来的地震构造研究取得了相当大的进展.

     

    Abstract: This paper reviews briefly the progressesmade during the last four years (1999~2002) in study of seismotectonics inChina, especially appraises the achievements inthe fields of the crustal and uppermantle′s structure‚the active faults and tectonic setting of large earthquakes, the crustal deformation, and the numerical simulation.Most earthquakes occurred in China belong to the continental earthquakes.Therefore‚Chinese seismologists pay more attention to the continental earthquakes.Based on improvements of the observation systems in theChinese ninthFive-YearPlan, the studies on seismotectonics have achieved great progresses.
