| 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１０００年，对应０～１６８ｃｍ沉积物的磁化率－地震剖面与近５００年以来有记载的重大历史地震事件检验相吻合。发现距今５００～１０００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。 |
| 关 键 词： | 环境磁学 沉积物 磁化率 历史地震 |

| 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 |
| Keywords: | Environmental magnetism deposit susceptibility historical earthquake Fuxian Lake in Yunnan |
