提出余震序列动态模拟及三维地形可视化功能的实现方法和关键技术，以ArcEngine为开发组件，实现数据管理、专题查询、余震地震序列动态模拟、地形分析、三维浏览显示等功能，建立基于ArcEngine的应急三维可视化系统。在2011年云南缅甸7．2级地震、盈江5．8级地震应急响应中，系统在余震序列动态模拟生成、三维地形模拟显示、影响场破裂方向初判及宏观震中判定上取得良好效果。

英文摘要：

In this paper, we proposed the key techniques and methods for the dynamic simulation o{ the aftershock sequence and the realization of the three-dimensional visualization. Then, using AreEngine platform, we developed a three-dimensional visualization system which has functions such as data management, subject inquiry, topographic analysis, three-dimensional display and browse, dynamic simulation of the aftershock sequence. We applied the system to the emergency response of the Ms 7.2 earthquake in the China-Burma border region, and the Yingjiang, Yunnan, Ms 5.8 earthquake in 2011. The results given by the system such as dynamic simulation of the aftershoek sequence, display of the simulated three-dimensional topography, preliminary estimation of the direction of earthquake-influenced field, and the macro-epicenter, were proved correct.
