A comprehensive Historical Tsunami Database (HTDB) for the World Ocean has been compiled and is being maintained as part of the joint IUGG/TC and ICG/ITSU Project “Global Tsunami Catalog and Database”. The database consists of two main parts: the catalog of tsunamigenic events with their basic source parameters and the catalog of the observed run-up heights. The current version of the database covers the period from 2000 BC to present time and contains 2270 entries in the tsunamigenic event catalog and over 10500 run-up heights provided with the exact geographical coordinates of the observational sites. A set of collected parameters of tsunamigenic events includes date, time, coordinates of the epicenter, source depth, surface-wave and moment-magnitudes, Abe’s tsunami magnitude, tsunami intensity (on the Soloviev-Imamura scale), the maximum tsunami run-up height, the number of available run-up observations, a cause of the tsunami, validity of the event, coded name of the source region and the main reference to the event.
Location map of the sources of historical tsunamigenic events. Size of circles is proportional to the event magnitude, color represents the tsunami intensity on Soloviev-Imamura scale.
