A Review of Research Methods and Evolution Mechanisms of Landslide-Induced Tsunamis

Abstract

The research on landslide surge has always been a hot issue in the research of engineering geology, geological disasters and hydraulics in both domestic and foreign circumstances. Based on the research status and achievements of landslide surge, this paper mainly reviews the research methods of landslide surge including numerical simulation methods, theoretical analysis methods and physical methods. The first part summarized the examples of geological disaster surge and the classification, characteristics and influencing factors of geological disaster surge. In the second part, the research methods of landslide surge are summarized. Firstly, the theoretical analysis progress of landslide surge in recent years is summarized. Secondly, the present situation of physical model test is summarized from four aspects: model, surge generation, surge propagation and surge run-up. Finally, the numerical simulation methods are summarized from the generation and propagation of surge. The third part discussed the influence factors of landslide surge. In the next part, the difficult problems and research status of landslide surge are evaluated. Finally, the study of landslide surge is prospected from the perspective of various factors of landslide surge.
