The Burckle crater is an undersea topographic feature about 29 kilometres (18 mi; 16 nmi) in diameter[1] in the southwestern Indian Ocean.
It is east of Madagascar and west of Western Australia, adjacent to the mid-ocean Southwest Indian Ridge.
Burckle Crater's position was determined in 2006 by the Holocene Impact Working Group using prehistoric chevron dune formations in Australia and Madagascar.
Based on a hypothesis that these dunes were formed by a megatsunami resulting from an impact, the researchers were able to triangulate the location of Burckle Crater.
In 2009, geologists Jody Bourgeois and R. Weiss challenged the hypothesis that a megatsunami created the chevron dunes.
