Earthquakes, Crustal Deformation, and Plate Tectonics at Convergent Plate Boundaries

本研究将在板块构造的框架内对会聚板块边界的地震变形进行系统的、全球性的研究。在收敛的板块边界观测到的地震变形模式往往不符合最简单形式的板块构造理论。这项工作将利用地震震源机制的目录和汇编，以及关于晚第四纪断层偏移率的地质数据。拟议工作的目标是开发一个在板块边缘及其附近的地震（瞬时）变形的全球调查或地图，可以与板块构造模型预测进行比较，并希望在不久的将来，随着天基大地测量（GPS和VLBI）调查的进展，大量的大地测量将变得可用。这项研究是国家减少地震危害计划的一个组成部分。

This research will do a systematic, global study of seismic deformation at convergent plate boundaries within the framework of plate tectonics. The patterns of seismic deformation observed at convergent plate boundaries are often not in accord with plate tectonic theory in its simplest form. The work will make use of catalogs and compilations of earthquake focal mechanisms as well as geological data regarding rates of late Quaternary fault offsets. The goal of the proposed work is to develop a global survey or map of seismic (instantaneous) deformation at and in the vicinity of plate margins, which can be compared with plate tectonic model predictions and, hopefully, in the near future, large numbers of geodetic measurements that will become available as space-based geodetic (GPS and VLBI) surveys progress. This research is a component of the National Earthquake Hazard Reduction Program.
