在地震发生后，快速估计城市结构的损失可以促进迅速、有效的灾后措施。基于物理的城市地震模拟，使用测量的地面运动作为输入，是获得合理估计的一种可能的方法。这种估计的困难在于进行模拟，并在有限的时间内对大尺度时间序列的结果进行透彻的理解。我们开发了一个基于快速城市地震灾害模拟的评估系统，并提出了一种适用于GPU工作站的交互式可视化方法。使用该系统，一个拥有10万多个结构的城市区域可以在一小时内进行分析并以可视化的方式进行交互。
In the immediate aftermath of an earthquake, quick estimation of damage to city structures can facilitate prompt, effective post disaster measures. Physics based urban earthquake simulations, using measured ground motions as input, are a possible means of obtaining reasonable estimates. The difficulty of such estimation lies in carrying out the simulation and arriving at a thorough understanding of large scale time series results in a limited amount of time. We developed an estimation system based on fast urban earthquake disaster simulation, together with an interactive visualization method suitable for GPU workstations. Using this system, an urban area with more than 100,000 structures can be analyzed within an hour and visualized interactively.
