A Kinematically and Geometrically Validated 3-Dimensional Model of Active Faults in the Northridge Area Constrained by Earthquakes and Geologic Data

小行星9416222 该项目结合了三个领域的专业知识，同时应用地震和地质约束，为北岭地区建立三维变形模型。 将使用最先进的可视化和建模算法，该算法允许结构的形状和运动学在所有方向上变化，并在三维中应用变形约束。 来自石油工业的地表和近地表数据将与北岭余震数据和先前地震活动的数据相结合。 这些数据将被纳入由合作者构建的横截面中，以允许计算横贯山脉-洛杉矶盆地的收敛率，以及隐藏推力的滑动量和滑动率。 这项研究的结果将大大有助于了解地下结构的洛杉矶和圣费尔南多山谷，并将提供急需的几何和运动学的限制地震灾害的解释。

9416222 Seeber This project combines expertise in three areas to apply simultaneously earthquake and geologic constraints in the construction of a three-dimensional deformation model for the Northridge area. A state-of-the-art visualization and modelling algorithm will be used which allows the shape and kinematics of structures to vary in all directions and applies deformation constraints in three dimensions. Surface and near-surface data from the oil industry will be combined with Northridge aftershock data and data from prior seismicity. These data will be incorporated into the cross-sections constructed by collaborators to permit calculation of the convergence rates across the Transverse Ranges-Los Angeles Basin, and the amount of slip and slip rates of hidden thrusts. The results of this study will greatly assist understanding of the subsurface structures of the Los Angeles and San Fernando Valleys, and will provide much-needed geometrical and kinematic constraints for seismic hazard interpretations.
