【摘要】 红河断裂带是一条大型的走滑断裂带,该断裂带北起青藏高原东部,云南西北部,穿越越南北部,向东南延伸到南海,全长超过1000km。根据印支半岛前新生代的古地块与华南地块的接触关系,将红河断裂带分为海陆两段。断裂带自从第三纪以来,经历了左旋运动,右旋运动以及局部旋转,南北两段的活动性有一定的差异性,现今断裂带在最北端活动强烈,曾多次发生6级以上地震,南段现今活动较为平静。更多还原

【Abstract】 The Red River Fault Zone is a gigantic sliding fault zone beginning from the east of Qinzang plateau in the north to the northwest of Yunnan, and passing through the north of Vietnam, and then extending to South China Sea, the whole length is over 1000km. Based on the contacted relationship between the old pre-Cenozoic massif in Indochina Peninsula and the South China massif, the Red River Fault Zone was divided into two parts extending from land to ocean, north and south segments. Since the Tertiary period, the Red River Fault Zone suffered the sinistral movement, dextral movement and local rotation. The activities of the north and the south segments were different. The activities of the north segment were violent at the end of the north in modern time where many earthquakes M≥60 occurred, today the activities of the south segment are calmer.更多还原
