根据灰色系统的一阶灾变模型，对台湾海峡7．3级地震的ML≥5．0级余震进行了预测，给出了未来可能的发震时间；根据汕头市国际大酒店地下室记录的这次地震的地面加速度时程，反演计算得到了基岩加速度时程，据此进行了地震反应分析，并对地基震害作了分区。
According to the first-order catastrophe model of gray system, the ML≥5.0 aftershock of the 7.3 magnitude of the Taiwan Strait earthquake is predicted, and the possible seismogenic time of the future is given. According to the record of the basement of Shantou International Hotel The acceleration time history of the earthquakes and the acceleration time history of the bedrock are obtained by inversion. According to the above, the seismic response analysis is carried out, and the foundation damage is zoned.
