About
This dataset offers essential information on global tsunami events from 1900 to the present. It encompasses key details such as the date, time, location, and magnitude of each event. Beyond basic event parameters, it includes data on the tsunami's impact, including fatalities and injuries. The dataset is further enhanced with additional information like bathymetry data, which is useful for modelling tsunami wave propagation. It serves as a valuable resource for researchers and educators, aiding in the study of tsunami causes and effects, the development of propagation models, and the enhancement of preparedness and mitigation strategies. This collection of over 2,000 tsunami events is freely available, fostering greater understanding of these natural disasters.
