Editorial on the Research Topic Physics and modelling of land slidesDisasters triggered by landslides cause life losses and substantial devastation to communities in terms of effects on the economy, livelihoods, and infrastructure every year across the world. However, the causative factors and mechanisms underlying landslide initiation and dynamics must be better understood, as accurate modelling of landslide risk is an essential prerequisite for developing reliable control and mitigation strategies [1]. Landslide susceptibility is influenced by a broad range of factors [2], such as soil physics and geochemistry, geological setting, climate, atmospheric dynamics, biogenic feedbacks, and anthropogenic influences, which have profound interlinkages with each other over a broad period-and length-scales. Moreover, landslide risk assessment further hinges on correctly understanding communities ' local vulnerability and exposure [3].This Research Topic of articles on the Physics and Modelling of Landslides presents leadingedge work into the quantitative understanding of landslide processes and dynamics.A series of numerical simulations were carried out by Wang et al. for a better understanding of the dynamic response and failure modes of rock slopes containing weak interlayers subjected to earthquake excitation. They used the continuum-discontinuum element method considering the influence of seismic amplitude and weak interlayer inclination, to shed light on the formation mechanism of rock landslides with weak interlayers. Accordingly, the acceleration waveform and peak ground displacement amplification coefficient characteristics strongly contradict the landslide failure process. The combination of weak interlayers and seismic load causes multiple failure landslide modes.Aiming at understanding the influence of water content on the characteristics of long-term deformations and stability of soil-rock mixtures of the Dahua landslide located on the right bank of Lancang River, China, Jiang et al., and Wang et al. performed multi-stage shear creep tests of SRM samples with different water contents. Based on their analysis, it was suggested that there are three stages of creep deformation: transient, steady-state, and accelerated. Moreover, shear-creep deformation is controlled by fractures of large particles at low water content but by large particles at high water content rotations.By looking at the combined effects of the debris-flow impact force and lateral Earth pressure through finite element analysis, Eu et al. modelled internal stresses experienced during debris flow and sediment deposition from the 2011 Mt. Umyeon landslide, Seoul, the Republic of Korea. This approach provided valuable insights for the structural analysis and safety
