Submarine landslide is the most serious threat on both local and regional scales. Tsunami phenomenon induced by submarine slide has put us on the challenge in understanding from generation mechanism to propagation and coastal inundation and mitigating the risk from it. Submarine slides can trigger tsunamis with high run-up affecting offshore structures, subsea facilities and human lives along the shoreline. Unfortunately, there are no effective numerical models that could simulate simultaneously all stages of generation, propagation and run-up of tsunamis phenomena. This paper presents a comprehensive review on the landslide tsunami phenomenon. © (2014) Trans Tech Publications, Switzerland.
