Earth Impact Database maintained by the Planetary and Space Science Centre, University of New Brunswick, Canada contains the data on nearly 200 confirmed Earth impact structuresDavid Rajmon's Impact Database. A massive data base of 661 suspected Earth impact craters compiled by the Impact Field Studies Group (IFSG) Chiemgau Impact Research Team (CIRT) Web-site contains materials of studying the strewn field of meteorite craters in Southern Germany (near Lake Chiemsee) that formed in the Holocene Chiemgau impact event possibly in the 6th or 5th century BC.Expert Database on the Earth Impact Structures (EDEIS) has been developed and is being maintained by the Tsunami Laboratory of the  Institute of Computational Mathematics and Mathematical Geophysics, Siberian Division, Russian Academy of Sciences. The database contains data on more than 840 structures with different validity index (relating to the degree of confidence to cosmogenic origin of a struvture) that  varies from 4 (definite) to 0 (false entry).Expert Database on the Earth Impact Structures old shell versionHistorical Tsunami Database for the World Ocean (HTDB_WLD) has been developed and is being maintained by the Tsunami Laboratory of the  Institute of Computational Mathematics and Mathematical Geophysics, Siberian Division, Russian Academy of Sciences. The database contains the basic parameters of 2270 historical tsunamigenic events occurred in the World Ocean  from 2000 BC up to the present time and  almost 10,000 coastal run-up and tide-gauge observations.Historical Tsunami Database for the World Ocean old shell version  |  |
