A REVIEW ON STUDY OF ACTIVITY OF XIANSHUIHE FAULT ZONE SINCE THE HOLOCENE
-
摘要: 鲜水河断裂带是中国西南山区一条现今活动强烈的大型地震断裂。本文在系统总结前人研究成果的基础上, 结合野外地质调查, 综述了鲜水河断裂带空间展布特征、活动性质及强度、历史地震地表破裂特征、地震危险性等方面的研究进展。前人研究结果表明, 鲜水河断裂带以惠远寺为界可分为两段, 进一步可细分为八段;断裂带全新世以来以左旋走滑为主, 兼具逆冲性质;整条断裂现今走滑活动速率约为10mm/a左右, 垂向变形在2mm/a以内;其中断裂带北西段活动速率为10~20mm/a, 南东段则小于10mm/a, 一般为5mm/a左右;断裂带地震活动频繁, 地震活动性北西段明显高于南东段, 强震迁移呈明显的跳跃式特征并具有原地复发性质;断裂带历史地震地表破裂特征与玉树地震所报道的地表破裂特征一致;断裂带地震危险性评价具很多不确定因素, 研究程度相对较低。Abstract: The Xianshuihe fault zone is a large active seismic-genetic zone in mountainous regions of southwest China. Based on previous studies, in combination with field investigation, the authors systemically summarized the research status about Holocene activity of Xianshuihe fault zone. The fault zone is divided by the Huiyuan Temple into two segments, the northwestern and southeastern segments, which are sub-divided into eight parts. Since the Holocene, the fault has occurred as a strike slip fault with thrust characteristic. The whole strike-slip generally displays an activity rate of about 10mm/a and a vertical deformation of 2mm/a or less. The activity rate is changeable in the fault, e.g., 10~20mm/a in the northwestern segment but smaller than 10mm/a in the southeastern segment. Accordingly the seismic activity is significantly stronger in the northwestern segment than in the southeastern segment. The earthquakes occurred with skip metastasis and have recurrent nature in situ. The surface rupture characteristics recorded in the historical earthquakes are consistent with those reported in the earthquake surface rupture. The research on seismic risk assessment along the Xianshuihe fault zone needs to be greatly improved.
