ITR/IM/AP: Websim 3D - A web-based system for generation, storage and dissemnination of earthquake ground motion simulations.

0113377Olsen这是一个开发和实现基于网络的“社区模型”（websim3D）的项目，用于生成、存储和传播地面运动模拟结果。 Websim3D最初将基于P.I.为洛杉矶盆地进行的九次长周期有限差分（FD）地震情景模拟。 用户可以方便地访问模拟地面运动时程，这将使地震学家和工程师能够分析宽带合成地面运动，以满足感兴趣地点的地震场景。被认为是使用南加州地震中心（SCEC）社区三维地震速度模型模拟南加州地震地面运动的权威。 他之前的工作为这种类型的模拟设定了标准。 为科学和工程界提供最先进的地震场景地面运动模拟是一个高度优先事项，特别是对于加州南部的洛杉矶地区，该地区占全国地震风险的25%。

0113377OlsenThis is a project to develop and implement a web-based "community model" (websim3D) for the generation, storage, and dissemination of ground motion simulation results. Websim3D will initially be based on the nine long-period finite-difference (FD) earthquake scenario simulations carried out for the Los Angeles basin by the P.I. The user-friendly access to the simulated ground motion time histories will allow seismologists and engineers to analyze the broadband synthetic ground motions for desired earthquake scenarios at sites of interest.The P.I. is regarded as an authority on simulation of ground-motion for southern California earthquakes using the Southern California Earthquake Center (SCEC) Community 3-D seismic-velocity model. His prior work set the standard for this type of simulation. Getting state-of-the-art ground-motion simulations for scenario earthquakes to the scientific and engineering community is a high priority, especially for the Los Angeles region of southern California, which contains 25% of the nation's seismic risk.***
