中文摘要
随着来自全球数字地震台网的高质量数字地震记录的出现,以及我们对这些数据进行震源特征反演的分析和计算能力的增强,更精细地探测地震破裂期间的粗糙度分布成为可能。为了更好地了解构造环境对破裂过程的影响,我们建议研究1-30秒周期的大地震的震源特征。我们希望比较几个不同带的浅俯冲地震、俯冲带向海的大洋岩石圈内的外升地震以及中深地震的震源谱、震源时间函数和矩释放的空间分布。
英文摘要
With the advent of high-quality digital seismograms from the Global Digital Seismic Network, and with our increasing analytic and computational ability to invert such data for earthquake source characteristics, it is becoming possible to probe more finely the asperity size distribution during rupture of an earthquake. In order to gain a better understanding of the effect of tectonic setting on rupture process, we propose to investigate source characteristics of large earthquakes at periods of 1 to 30 seconds. We wish to compare source spectra, source time functions, and spatial distribution of moment release for shallow subduction earthquakes from several different zones, outer-rise earthquakes that occur within oceanic lithosphere seaward of subduction zones, and intermediate and deep earthquakes.
