【摘要】 介绍了2023年12月18日甘肃积石山6.2级地震的发生、震前预测、震后趋势判断、地震动参数设定，震区构造、震害特征和周边地震活动的基本情况，对地震发生日期的调制，相互构造影响作用进行了分析，对此影响未来发震的可能性也做了简单分析，认为与之相交的南边和北边断裂危险性会增加，尤其西秦岭北缘断裂处在甘肃东部段地震可能性增大。对地震区历次烈度区划(地震动区划)的设定进行了阐述和回顾。重点在此次地震产生灾害的基础上针对地震科学与社会政策提出建议。更多还原

【Abstract】 The occurrence, pre earthquake prediction, post earthquake trend judgment, seismic parameter setting, seismic zone structure, seismic damage characteristics, and basic information of surrounding seismic activity of the 6.2 magnitude earthquake in Jishishan, Gansu on December 18, 2023 was introduced. The modulation of the earthquake occurrence date and the influence of mutual construction were analyzed, and the possibility of future earthquake occurrence was also briefly analyzed. It is believed that the risk of intersecting southern and northern faults will increase. Especially in the northern edge of the West Qinling Mountains, where the fault is located in the eastern section of Gansu, the possibility of earthquakes increases. The setting of seismic intensity zoning(seismic motion zoning) in previous seismic regions are elaborated and reviewed. Based on the disaster caused by this earthquake, some suggestions are proposed, including earthquake science and social policies.更多还原
