A comprehensive global catalog of landslide-triggered tsunamis (LTT) was compiled by reviewing tsunami and earthquake databases, catalogs, and scientific literature. This dataset is designed to investigate the relationship between tsunami heights and the triggering landslides' characteristics, including 354 documented cases from 6200 BC to 2024. It provides detailed information on landslide characteristics, triggering and preparatory factors, type of waterbody, tsunami wave height, inundation distance, and associated effects.
