9418643 Lay This research involves the use of broadband seismic data to address fundamental questions about earth structure and earthquake rupture processes. The areas to be studied include short-period analysis of layering near subduction zones, deep slab energy focusing effects and associated slab structure, tectonic analysis of new aspherical global shear-wave models, development of unified seismic source models from body wave and surface wave data. The results apply to convection in the mantle which is the driving force of plate tectonics, and to details of the generation of seismic waves in a multiple rupture earthquake process. This research is a component of the National Earthquake Hazard Reduction Program. *** ??

小行星9418643 这项研究涉及使用宽带地震数据来解决地球结构和地震破裂过程的基本问题。 研究领域包括俯冲带附近成层的短期分析、深层板片能量聚焦效应和相关板片结构、新的非球面全球剪切波模型的构造分析、根据体波和表面波数据开发统一的震源模型。 结果适用于作为板块构造驱动力的地幔对流，以及多重破裂地震过程中地震波产生的细节。 这项研究是国家地震减灾计划的一个组成部分。 *** ??
