【摘要】 在掌握西藏南部(26°～32°N,78°～98°E)19次历史地震数据后,从时间对称性方面研究该区域历史地震发生规律,分析未来地震发生的可能时间,从而为西藏地震灾害的监测提供一定的依据。从三元、四元和五元可公度信息提取法和蝴蝶结构法进行分析,得出未来10年内,西藏南部Ms≥6.6级地震的信号在2012年、2013年和2015年较强,有发生6.6级以上地震的可能。更多还原

【Abstract】 Historic earthquake activity in Tibet has been analyzed by the time symmetry based on the 19 times historical seismic data of southern Tibet(26°~32°N,78°~98°E),and predicted the time of the future earthquake occurrence and provided the basic reference for earthquake monitoring in Tibet.Based on the method of commensurability information extract including ternary,quaternary and quintuple and butterfly structure,the results show that in the next 10 years,there is a probability of Ms≥6.6 earthquakes occurred in southern Tibet in 2012,2013,2015.更多还原
