Abstract
AbstractLandslide-induced tsunamis pose a significant natural hazard with the potential for devastating impacts on coastal communities. This paper discusses the development and application of the LS-Tsunami simulation code, which utilizes landslide motion data from LS-RAPID to model these tsunamis. The program is compatible with Windows PC and features user-friendly visual interfaces and 3D graphical results, making it easy for beginners to conduct integrated landslide and tsunami simulations. The process involves setting the simulation area, editing topographic data, reading landslide results from LS-RAPID, and configuring calculation conditions. In addition to the descriptive steps provided in this paper, a video tutorial is available to guide users through the process of using the LS-Tsunami simulation code. Notably, LS-Tsunami has been successfully applied to various case studies, including a simple coastal landslide-induced tsunami, the 1972 Unzen landslide-induced tsunami in Japan, and a landslide-induced tsunami-like wave in Vietnam.
