第四系地层对地震地表破裂的影响主要取决于第四系地层的土动力学性状、不均匀性和土层厚度等因素。
The main influencing factors of Quaternary layers contain the dynamic indexes of layers, uneven distributions of layers and the layers thickness.
讨论了华北平原周边1975年海城地震、1937年荷泽地震及1830年磁县地震3次强震的地表地震破裂特征以及这3个地区北西向断裂的全新世活动。
The characteristics of the surface fractures of 1975 Haicheng earthquake, 1937 Heze earthquake, 1830 Cixian earthquake and activity of Holocene faults in those areas have been discussed in this paper.
震区的地表地震变形主要表现为地震破裂、滑坡和地震断层三种形式。
The Surficial deformation caused by the earthquake is mainly expressed as earthquake fractures, landslides and earthquake faulting.
当断层在地球内部的错动到达地球表面时所形成的地表破裂。并不是所有的地震都会形成地表破裂。
Surface rupture occurs when movement on a fault deep within the earth breaks through to the surface. NOT ALL earthquakes result in surface rupture.
地震震源处，其温度和压力与地壳浅处及地表不同，温、压越高，共轭破裂角越大。
The temperature and pressure at the focus is different from the shallow of the crust and the ground. The higher temperature and pressures, the larger conjugate rupture angle.
地震可以引起浅层裂缝——包括诱发性滑坡、横向拉伸型滑坡或其他形式的地表破裂。
Shallow crevasses can form during earthquake-induced landslides, lateral spreads, or other types of ground failures.
根据昆仑山口西地震测线断层围陷波的观测结果，可推断该处破裂面宽度为300m左右，远远大于地表破裂带的宽度。
Based on the fault zone trapped waves observed in Kunlun Mountain Pass region, the width of the rupture plane is deduced to be about 300 m and is greater than that on the surface.
地震的地表破裂中心在南冲、陆良山一带。
The center of surface rupture to the earthquake is located around Nanchong and Luliangshan.
