Historical Tsunami Database (HTDB)

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.
