孕震区 meaning in English

seismogenic zone

Analysis of a great many data shows that some strong earthquake will arouse seismogenic zone loading and bring the increase of stress , accelerate accumulation of nonlinear strain of medium . it will make the earthquake source rupture of high stress status in unsteadiness in advance , which resulting the proceeding earthquake occur in advance
表明：某次强震活动可以引起某些孕震区的加载，介质非线性应变积累加速，使处于高应力状态的震源失稳提前进入不稳定状态，后续强震提前发生，即强震之间存在着时间、空间上的关联性。
