摘要
从地震活跃幕、地震活动相关性和时空强特征演变等多个方面探讨了东南沿海地震带近期的地震形势,认为该带第四个中强地震活跃幕已经在1999年结束,目前正处于第五个平静幕的中期或后期阶段,短时间内发生6级以上地震和5级以上地震丛集活动的可能性较小,未来1～2年内,有发生5级左右地震的危险。
The earthquake situation in the near future of the Southeastern Coastal Seismic Belt is discussed from seismic active episode,seismic active correlativity,time-space-strong characteristic evolvement,etc.We think the fourth mid-strong seismic active episode of the belt ended in 1999.Now,it is in the medium term or upper stage of the fifths quiet episode,the possibility of earthquakes with M>6 and M>5 crowd together occurring is small in the short time.There is seimic risk that earthquakes about 5 occur in the future 1～2 year.
