摘要: 根据地震复发周期模型, 利用现有的地质构造等资料把南北地震带划分为若干相对独立的活动构造区, 对能量积累阶段及地震危险性的预测建立相应的数学模型, 并构建基于WebGIS的网络计算平台, 由客户端任意在研究区选择构造分区, 并输入所选构造分区相应的计算参数, 提交到集群服务器计算模型进行计算, 对所选构造分区的地震危险性阶段及潜在震级进行预测并把结果以WebGIS方式返回给客户端。 实现了利用远程计算技术与并行算法对活动断裂能量积累与释放过程的模拟计算, 其结果可以为判定地震中短期预测的地点和震级提供依据。

Abstract: Based on earthquake recurrence cycle model, using seismic parameters and characteristics of the seismic activity, the north-south seismic belt were divided into several seismogenic tectonic areas, the model for seismicity risk prediction based on seismic energy accumulating stage theory was set up, and the national seismic network computing application system was constructed based on WebGIS. The clients can select seismogenic tectonic areas and input seismic parameters, and then submit job to cluster server. The energy accumulating stage and magnitudes of potential earthquakes was calculated, the result sent to the clients via WebGIS. The platform which fulfills analogy computing of accumulating and releasing characteristics of seismic tectonic energy, can be used to estimated quantitatively the magnitudes of the potential earthquake of some seismogenic tectonics.

Key words: WebGIS, Energy accumulating and releasing, seismogenic tectonics, Seismic risk estimation
