宽频带地震学与中强地震破裂过程的研究

宽频带地震学是近年来地球物理学科的重要进展之一，现代的观测技术实现了仪器在很宽的频带范围内记录数字地震信号，宽频带资料含有更真实和更全面的震源和地下介质的信息，利用宽频带资料可以对广泛的地球物理问题进行研究，中强地震的破裂过程是一个非常重要的研究课题。利用宽频带地震学的分析手段，可以得到更加精细的破裂图象，未来的十年里，宽频地震学将会是地震学发展的一个主要方向。

BROADBAND SEISMOLOGY AND STUDIES ON THE RUPTURE PROCESS OF INTERMEDIATE AND LARGE EARTHQUAKES

Broadband seismology is one of important progresses in Geophysics sciences in recent years. Modern observation technique makes that instrument could record digital seismic pulse in range of very board band. Broadband data have more information about source and ray path. So wide Geophysics problems might be researched by using broadband data. The rupture process of inteimediate and large earthquakes is a very important research problem. The rupture pattern could be seen in more detail by the analysis method from broadband seismology. In next ten years, broadband seismology will be one of main developing fields of seismology.
