Collaboration: Toward Unified Seismic Source Models: Joint Body Wave and Surface Wave Inversion Methods

本研究是一项合作研究，旨在开发震源体波和面波同步反演方法。目标是利用地震和大地测量的整个频谱获得地震破裂过程的统一描述。目前，即使是对不同类型的波（如体波和面波）进行最复杂的分析，也经常得出不一致的断层参数。这种不一致应该通过关节反演来解决。这项工作将融合三种不同的体波反演方法，每种方法都适用于某一类地震破裂，并采用高分辨率、基模表面波谱反演技术。这项研究是国家减少地震危害计划的一个组成部分。

This research is a collaborative effort to develop simultaneous body-wave and surface-wave inversion methods for the earthquake source. The goal is to attain unified descriptions of earthquake rupture processes using the entire spectrum of seismic and geodetic measurements. Currently, even the most sophisticated analyses of different wave types (e.g., body waves and surface waves) often yield inconsistent fault parameters. This inconsistency should be resolved by joint inversion. The work will merge three different body-wave inversion methods, each appropriate for a certain class of earthquake rupture, with high-resolution, fundamental-mode surface-wave spectral- inversion techniques. This research is a component of the National Earthquake Hazard Reduction Program.
