摘要
选取10种物理意义清楚、独立性较好的地震活动性参数,以最大限度地提高预报效能为目标,采用全时空扫描方法建立动态寻优预报模型。研究表明,地震活动性参数动态寻优预报模型,在空间上,客观地反映了区域构造活动的差异性;在时间上,完整地反映了区域地震活动的涨落;可以有效地剔除背景干扰,提高地震异常识别率,避免预报的随机性和盲目性。
10 seismic activity parameters, which is independent of each other with clear physical meaning are selected in the paper. In order to search a prediction model, the spatial-temporal scanning method for selected seismic parameters has been used. The results show that the prediction model established based on the scanning approach reflects the tectonic differences of each region objectively in space, and reflects the seismic fluctuation in time completely also. It can improve the capability of identifying the seismic abnormal phenomena
