"NERC : Nicholas Dodds : NE/L002612/1"This research project aims to develop a novel approach to improve the measurement of 3D displacement fields from earthquake surface deformation, by combining established independent complementary techniques (Differential LIDAR (D-LIDAR) and Optical Image Correlation (OIC)). These 3D displacement fields provide information on both the fault geometry and mechanics of earthquake deformation, with especially valuable insight into earthquake ruptures within the shallowest portions of the crust. The techniques developed will be applied to two recent high impact earthquakes, the 2014 South Napa M6.1, and the 2019 Ridgecrest M6.4/7.1 Sequence, both in California, to improve our understanding of the rupture mechanics in these earthquakes.

“NERC：Nicholas DODS：NE/L002612/1”这项研究项目旨在开发一种新的方法，通过结合已有的独立的互补技术(差分激光雷达(D-LIDAR)和光学图像相关(OIC))来改进地震表面变形的3D位移场的测量。这些3D位移场提供了有关断层几何和地震形变机制的信息，对地壳最浅部分的地震破裂有特别有价值的洞察。开发的技术将应用于最近两次高影响的地震，2014年南纳帕6.1级地震和2019年里奇克雷斯特6.4/7.1级地震，这两次地震都在加利福尼亚州，以提高我们对这些地震中的破裂机制的理解。
