The Web versions of the Historical Tsunami Databases for the World Ocean (HTDB/WLD), and Expert Database on the Earth Impact Structures is maintained by the Novosibirsk Tsunami Laboratory (NTL) which is part of the Institute of Computational Mathematics and Mathematical Geophysics of Siberian Division of Russian Academy of Sciences.

• HISTORICAL TSUNAMI DATABASE FOR THE WORLD OCEAN (new shell, pilot version)

The database contains the source some basic tsunami parameters on almost 2270 historical tsunamigenic events occurred in the World Ocean (within the area between 90S to 90N and 180E to 180W) from 1628 B.C up to the present time, nearly 9000 coastal run-up and tide-gauge observations of wave heights and the last part ( earthquake data ) contains the world-wide catalog of significant earthquakes (nearly 6300 events) from pre-historic times till present. The site provides you with screen forms for data search by a number of criteria, for their listing, sorting and for several types of data processing (a histogram of tsunami occurrence, intensity-time and intensity-magnitude charts).
• EXPERT DATABASE ON THE EARTH IMPACT STRUCTURES
  The database contains the information about impact structures of the Earth (Only 1117 craters), such as geographical coordinates, age, diameter and another.
