Dhala crater (N25°17'59.7" and E78°8'3.1") is a crater formed by an asteroid impact.[1] It is situated in Shivpuri district, Madhya Pradesh India and is the second such crater found in India, after Lonar lake.[2] The diameter of the structure is estimated at 11 km and basement rocks are predominantly composed of granitoids. It is estimated that the impact occurred between 1.6 and 2.5 Ga[3] or about 2,500 million years ago. It is 240 km from the Ramgarh crater, the location of 11th century Bhand Deva Temple being renovated by INTACH in 2018.
Largest in India
Dhala crater is considered as the largest in India as well as between the Mediterranean and Southeast Asia.[2][3] The crater is considered a "large complex impact structure" with an estimated diameter extending up to 25 km.[4] Dhala is the largest impact structure currently known in the region between the Mediterranean and southeast Asia.
