Here, we present two links to databases of Earth impact structures
Impact structures of the world, compiled by Jarmo Moilanen (2009)
http://www.somerikko.net/impacts/database.php
and
Expert Database on Earth Impact Structures (EDEIS) of the
Institute of Computational Mathematics and Mathematical Geophysics SD RAS Tsunami Laboratory (2008)
http://tsun.sscc.ru/nh/impact.php
These databases are by far more comprehensive than the Canadian Earth Impact Database which has time and time again got talked about not so much because of its set of criteria as because of its application frequently inexplicable. The Canadian database seems to have lost its former reliability and we can’t help thinking that personal connections take precedence over scientific significance.
This becomes especially evident with regard to the large Spanish Azuara and Rubielos de la Cérida impact structures which are still disqualified from the Earth Impact Data Base at the University of New Brunswick (Canada) managed by John Spray.
Characteristic of John Spray’s odd understanding of science: In a written inquiry Ferran Claudin asked him why the Azuara structure formerly established as a proven impact had been eliminated from the data base and why also Rubielos de la Cérida despite overwhelming impact evidence has not been recorded. Moreover, Ferran offered to send him reprints of all published articles on the impacts. John Spray wrote back that Ferran were free to do it but that he, John Spray, would not read the articles.
So much about the so-called “impact community” and the obstruction of science by a small group of persons, which does not only concern the Spanish impacts but can also be stated on all continents and with other impact research projects. In the submenu “Controversy” of our website we in detail consider the in part incredible processes accompanying the case of the Spanish impact structures
