Dhala crater
Dhala crater (N25°17'59.7" and E78°8'3.1") is a crater formed by an asteroid impact.[1] It is situated near Bhonti village in Pichhore block of Shivpuri district of Madhya Pradesh state in India.[2] It is the largest crater in India,[2] and between the Mediterranean and Southeast Asia. The diameter of the structure is estimated at 3 km,[3] while other sources estimate its diameter to be 11 km diameter. It is the second such crater found in India, after Lonar lake.[2]
It is 200 km east of the Ramgarh crater, the location of 11th century Bhand Deva Temple which was renovated by INTACH in 2018.
Impact date[edit]
It is estimated that the impact occurred between 2.44 and 2.24 Ga.[4] Basement rocks are predominantly composed of granitoids.
Largest in India[edit]
This crater on the Bundelkhand craton is the largest crater in India.[2][5]
