Continental Kinematics: Asia, New Zealand and the Rest of the World

9316581霍尔特这项研究涉及亚洲、伊朗、新西兰和日本等地区变形大陆岩石圈的运动学调查。板块运动是地球上一个重要的过程，因为它们几乎是所有观测到的地表变形的原因。虽然刚性板块模型在匹配全球观测数据方面做得很好，但大陆岩石圈内的相对运动模型要复杂得多。然而，相对运动，或速度梯度张量，是理解变形动力学，特别是地震危险的基础。具有足够变形速率数据的区域内的应变率将使用连续的函数集(如样条线)进行建模。其目标是显著促进对大陆岩石圈几个复杂区域的运动学和动力学的理解。这项研究是国家减少地震灾害计划的一部分。***

9316581 Holt This research involves the investigation of the kinematics of deforming continental lithosphere in regions such as Asia, Iran, New Zealand, and Japan. Plate motions are an important process on the earth since they are responsible for almost all of the observed surface deformation. While rigid plate models do an excellent job in matching observations globally, relative motion models within continental lithosphere are more complex. Yet the relative motions, or velocity gradient tensor, are fundamental to the understanding of the dynamics of deformation, especially seismic hazard. Strain rates within regions with adequate deformation rate data will be modeled using continuous sets of functions such as splines. The goal is to significantly advance the understanding of the kinematics and dynamics of several complicated regions of deforming continental lithosphere. This research is a component of the National Earthquake Hazard Reduction Program. ***
