通过对顺义地震的序列特征、地震活动与加卸载响应比等前兆异常的时空演化等方面的研究 ,认为顺义地震为一次非前兆性震群 ;震前存在地震条带、3级以上地震东移、南北向小震条带、响应比异常等地震活动异常以及以顺义板桥水位为主的破年变等前兆异常 ,这些前兆异常的时空演化过程表现出与中强地震类似的具有一定力学基础的三阶段特征 ,这些结果对北京及邻区的中等以上地震的预测研究与短临跟踪工作都具有重要的参考作用 Based on the research on the sequence features of Shunyi earthquake and the temporal and spatial evolution of precursor anomalies such as seismic activity and loading-unloading response ratio, it is concluded that the Shunyi earthquake is a non-precursory earthquake swarm. Before the earthquake, there were seismic bands and eastward , The north-south small earthquakes, the response anomalies and other seismic anomalies, and the Banishianbushui-like water level in Shunyi and other precursory anomalies, the precursory anomalies of the temporal and spatial evolution of the mid-strong earthquakes showed similar to have a certain mechanical basis These results have an important reference for the prediction and short-term follow-up of moderate-above-magnitude earthquakes in Beijing and its adjacent areas
