长江中下游-南黄海地震带地震趋势研究

STUDYON SEISMICITY TENDENCY FOR SEISMIC ZONE FROM MID-LOWER REACHES OF THE YANGTZE RIVER TO SOUTH YELLOW SEA

摘要:

运用灰色理论对长江中下游-南黄海地震带从1971年开始的20世纪第2个地震活跃幕的结束时间进行了研究.结果表明,该次地震活跃幕的结束时间大约在2019年.还运用灰色理论对该地震带未来的地震形势进行了预测.所得结果可供华东地区地震大形势分析和地震的中期预报参考.

Abstract:

The end-time of the recent earthquake active episode and future earthquake tendency for seismic zone from mid-lower reaches of the Yangtze river to south Yellow sea are studied with the grey theory.The result shows that the end-time of the episode is about 2019 year.The conclusions obtained can be taken for reference in analysis of earthquake tendency and medium-term prediction of earthquake of east China.
