【摘要】 首次将环境磁学磁化率特征方法应用于历史地震研究 ,阐明了云南抚仙湖沉积物磁化率突变与地震事件的相关性。所建立的时限近 10 0 0年 ,对应 0～ 16 8cm沉积物的磁化率—地震剖面与近 5 0 0年以来有记载的重大历史地震事件检验相吻合。发现距今 5 0 0～ 10 0 0年抚仙湖地区的 8次未被记载的地震事件 ,指出发震的年代范围 ,对抚仙湖地区近千年的历史地震进行回溯。更多还原

【Abstract】 It is the first time to study historical earthquakes by method of environmental magnetic susceptibility It has discussed the relativity between mutation of susceptibility of deposit in Fuxian Lake and seismic events A profile of susceptibility of deposit for 0-168 cm and seismic events has been established, which is coincided with the important seismic events recorded for 500 years Eight unrecorded seismic events 500-1000 years ago in Fuxian Lake have been discovered Ages of seismic events are also reviewed更多还原
