Simulating, Verifying, and Predicting Three Dimensional Resonance and Focusing in Salt Lake Valley

本项目利用三维波动方程的数值模拟研究了盐湖流域的地面放大现象。利用有限差分技术在并行结构计算机上模拟了低频传播（0- 3hz）和共振。提供对地面放大问题的准确理解，这对改进分区图的开发和现有地面响应测量的验证具有直接影响。直接应用于减少地震危害的目标。

Project investigates the ground amplification phenomena in the Salt Lake Valley, using numerical simulation of the 3 dimensional wave equation. Low frequency propagation (0-3 Hz) and resonence is simulated using finite difference techniques on a parallel- architecture computer. Provides an accurate understanding of the ground amplification problem, which has direct impact on the development of improved zoning maps and verification of existing ground response measurements. Direct application to earthquake hazard reduction objectives.
