1·The results show that there are some anomalies in seismicities before the earthquake.
结果表明，震前的地震活动性表现出一定的异常。
2·The evolutionary trend of hydrochemical colony anomaly is closely related to seismicities.
水化群体异常的演化趋势与地震活动密切相关。
3·The seismicities of each sub-region are studied using the strain accumulating and releasing model.
应用地震应变能积累释放模型研究了各地震区的地震活动水平。
4·A single - station method for monitoring the dynamic changes of small seismicities and future strong earthquakes within the certain region around the station is introduced in this paper.
介绍了一种用单台地震资料，监视台站周围一定区域范围内，小震活动水平的动态变化，预报未来强震发生的方法。
