CRATER LINKS AND REFERECES

Impact craters are not to be confused with other landforms that in some cases appear similar, including calderas and ring dikes.

For an interesting visualization of what might happen if a 40 km diameter meteorite were to hit the earth see this video: http://www.youtube.com/watch?v=vdSTE4jWJmk.

An inventory of confirmed impact structures is maintained by the Earth Impact Database, which is an authoritative source of information.  The database, initiated in 1955 by the Dominion Observatory, Ottawa, currently (as of December 2012) lists 183 confirmed impact sites on earth.  This database can be accessed at:
