Crustal instability to induce the geohazards often results from both the internal tectonic dynamics and external sediment processes. Thus, the detailed geodynamics and kinematics of geohazards are important for understanding the tectonic evolutionary process and evaluating potential geohazards. This paper focuses on the active faults, submarine landslides, earthquakes as well as submarine canyons geomorphology description and kinetics explanation in the northern South China Sea (SCS) continental margin. Firstly, we have estimated the spatial extent, fault-plane geometry and faulting behaviors of the submarine active faults, such as the Littoral Fault Zone, based on cumulative deformation recorded by geophysical seismic reflections and geomorphic markers. We also analyzed the reactivation of preexisting structures, as well as the spatial and temporal distribution and migration of the submarine landslides and canyons. Then, several conceptual models and a comprehensive study of some of the different factors that contributed to the geohazard chain are conducted based on pre-existing theory and available literature. This review study indicates: (i) geohazards of different phases and geohazard chain are generally triggered by both early-phase tectonics-dominated and later-phase sedimentation-dominated processes; (ii) the fault geometric and stress segmentation may have played an important role in controlling on the uneven and asymmetric distribution of earthquakes and submarine canyons of the northern SCS, Especially, the ENE-striking preexisting Littoral Fault Zone is the major seismogenic structure along the Southchina coastline; (iii) the tectono-sedimentary coupling induced landslide and slope failure that has help to shape the modern coastal and slope geomorphology.

诱发地质灾害的地壳不稳定性通常是由内部构造动力学和外部沉积过程造成的。因此，地质灾害的详细地球动力学和运动学对于理解构造演化过程和评估潜在的地质灾害非常重要。本文重点研究南海北部(SCS)大陆边缘的活动断裂、海底滑坡、地震以及海底峡谷地貌描述和动力学解释。首先，我们根据地球物理地震反射和地貌标记记录的累积变形，估计了海底活动断层（例如沿海断裂带）的空间范围、断面几何形状和断层行为。我们还分析了预先存在的结构的重新激活，以及海底滑坡和峡谷的时空分布和迁移。然后，根据现有理论和现有文献，对一些概念模型和对地质灾害链的一些不同因素进行了综合研究。本综述研究表明： (i) 不同阶段和地质灾害链的地质灾害通常由早期构造主导和后期沉积主导的过程触发；(ii) 断层几何和应力分割可能在控制南海北部地震和海底峡谷的不均匀和不对称分布方面发挥了重要作用，特别是 ENE 走向的先存沿岸断裂带是沿线的主要发震构造。华南海岸线；
