Ecological Systems and Devices Annotation << Back Approaches to Numerical Simulations of Tsunamis Caused by Landslide Processes Tikhonchuk E.A., Kostenko I.S., Tolikina M.Yu. Estimation of the stability of natural slopes is the actual problem not only for engineering and geological surveys, but also for fundamental science. The article examines the theory of landslide modeling, describes the methods and approaches, and the main types of numerical models. The results of modeling the landslide process are submitted using the NAMI DANCE_L software package. The results of numerical calculations of underwater landslides located to the south-east of the Sakhalin coast are presented. The future prospects for the development of this field of science are related to the further improvement of existing models, and to the introduction of innovative technologies and the creation of integrated monitoring and risk management systems. Keywords: landslide, numerical simulation, tsunami, two-layer model. DOI: 10.25791/esip.11.2025.1555 Pp. 22-30.
