Earth Impact Database

The Earth Impact Database is the authoritative source for information on confirmed impact structures or craters on Earth. It was initiated in 1955 by the Dominion Observatory, Ottawa, under the direction of Dr. Carlyle S. Beals. It is now maintained as a not-for-profit source of information at the Planetary and Space Science Centre at the University of New Brunswick, Canada.

The database currently lists over 170 confirmed impact sites, all of which should be included in the list of impact craters on Earth.

Other comprehensive lists are wider in scope by including more than just confirmed sites, such as probable, possible, improbable and rejected impact sites on their lists. The reason to retain rejected sites is because they may be reported again. Sites will appear first in these lists while under study and may "graduate" to the Earth Impact Database after confirmation and collection of enough information about the site to satisfy the database's entry criteria.
