摘　　要：通过余震序列、震源机制解、地震构造背景分析了河北临城MS3.7地震的特征,根据现场调查了解了此次地震的影响范围并绘制了烈度圈,确定了震区一带的民居、医院学校房屋结构类型及其抗震性能,震区民房不设防,尤其是西边丘陵地区,房屋基础差,砌筑墙体中水泥含量少,应加快小城镇和农村抗震安居工程普及,加强村镇建筑工匠培训和防灾减灾知识宣传,切实提高公众防灾减灾意识和应对突发事件的应对能力。This paper analyzes the characteristics of MS3.7 earthquake in Lincheng,Hebei,through the aftershock sequence,focal source mechanism and seismic tectonic background. According to the onsite investigation,the impact range of the earthquake was understood and the intensity circle was drawn.The structural types and seismic performance of residential buildings,hospitals,and schools in the earthquake area were determined. Guidance and suggestions were put forward for earthquake prevention and disaster reduction in the earthquake area.
