活动构造带（active structural zones）即活动断裂带（active fault zone），是挽近地质时期乃至近代尚在持续或断续活动的构造带。其活动性可通过地质构造、地震活动、火山活动、构造地貌和第四纪地质、考古等调查，以及地形变、地应力和各种地球物理场观测等加以鉴别；影响最新地层是其最确切的标志。它是活动构造体系中变形显著、活动较强的地带，展布规律和活动强度均受所属构造体系及其构造应力场制约。
认为在活动构造带内，垂直差异运动过程中状态的变化是地震孕育，发生的重要因素。
It is concluded that the change of the states in the process of vertical motion in active tectonic belts is a important factor of yielding earthquakes.
另外，在强震震中沿活动构造带或沿块体边缘迁移时，迁移时间也有相隔5个月的现象。
In addition, when the epicenters of strong earthquakes migrated along the active tectonic zone or the edge of a block, a 5-month separation for the the migration was also observed.
长线工程场地一般都得穿经活动构造带，因而活动构造研究在该类场地的地震安全性评价工作中尤为重要。
Long line engineering sites usually have to pass through some active tectonics, so that the research of active tectonics is of great importance to seismic safety evaluation of this sort of site.
