震源时间函数与震源破裂过程

Source time function and rupture process of earthquake

简要介绍了现代数字地震学的两个重要概念,一个是震源时间函数,另一个是地震震源的时空破裂过程。首先,从地震断层位移表示定理出发,介绍震源时间函数和震源破裂过程的基本概念;然后,分别介绍两种从远场地震记录中提取震源时间函数和获取有限断层面上时空破裂过程图像的反演方法。

This paper briefly introduces two of the important fundamental concepts in modern digital seismology, the source time function and the source rupture process. At first, the two concepts are derived from the representation of the displacement caused by a seismic faulting, and then, two of the inversion approaches are described for retrieving source time function and imaging rupture process of a finite seismic fault.
