Burckle Crater is an undersea crater the Holocene Impact Working Group considered likely to have been formed by a very large scale and relatively recent (c. 2800-3000 BC) comet or meteorite impact event. It is estimated to be about 30 km in diameter, hence about 25 times larger than Meteor Crater.
It is located to the east of Madagascar and west of Western Australia in the southern Indian ocean. Its position was determined in 2006 by the same group using evidence of its existence from prehistoric chevron dune formations in Australia and Madagascar that allowed them to triangulate its location. But the theory that these chevron dunes are due to tsunamis has been challenged by geologist Jody Bourgeois; using a computer model to simulate a tsunami, she believes the structures are more consistent with aeolian processes.
Burckle Crater lies at Coordinates: 30.865°S 61.365°E in the Indian Ocean and is 3,800 m below the surface.
