1976年发生在中国华北平原北部的唐山MS7.8地震是中国东部近300年来发生的最大地震。该次地震发生之后,诸多学者报道了展布在唐山市南侧长约8～11 km的地震地表破裂带。该地表破裂带由十余条NE方向、具右旋走滑特征的地表破裂呈左阶型式组成,总体走向NE30°,最大右旋位移1.5～2.3 m,多数地段的垂直位移0.5～0.7 m。此外,众多学者对该次地震的形变特征、震源破裂参数、唐山地区第四纪断 The Tangshan MS7.8 earthquake that occurred in northern China in 1976 in northern China is the largest earthquake in eastern China in nearly 300 years. After the earthquake, many scholars reported that the surface rupture zone of the earthquake spreading in the south of Tangshan City is about 8 ~ 11 km. The surface rupture zone is composed of more than ten NE directions and dextral strike-slip features. The surface rupture has a left-order pattern with an overall strike of NE30 °, a maximum dextral displacement of 1.5-2.3 m and a majority of vertical displacement of 0.5-0.7 m. In addition, many scholars on the deformation characteristics of the earthquake, source rupture parameters, Tangshan Quaternary off
