中国华北地区大地震复发周期及迁移特征(英文)
RECURRENCE PERIODS AND MIGRATION CHARACTERISTICS OF GREAT EARTHQUAKES IN NORTH CHINA
【摘要】 以古地震、历史地震和现代地震作为时间域,以华北地区、山西地震带、河北平原地震带和郯庐地震带为单元,分析和研究了华北地区大地震复发周期和迁移特征.在此基础上,讨论了华北地区地震活动的动力学问题、块体框动、地震迁移和地震活动趋势.
【Abstract】 aking paleoearthquakes,historic and recent earthquakes as time domains,and North China,Shanxi seismic zone,Hebei plain seismic zone and TanchengLujiang seismic zone as units,authors analyze and study the recurrence intervals and migration characters of great earthquakes in North China.On this basis,a dynamic problem of seismic activity,block frame motion,earthquake migration and seismicity trend in North China are discussed.
