It is situated near Bhonti village in Pichhore block of Shivpuri district of Madhya Pradesh state in India. It is the largest impact structure in India, and between the Mediterranean and Southeast Asia. The diameter of the structure is estimated at 3 kilometres (1.9 mi), while other sources estimate its diameter to be 11 km diameter. It is the second such structure found in India, after Lonar lake.

It is 200 km east of the Ramgarh crater.

Impact date

It is estimated that the impact occurred between 2.44 and 2.24 Ga. Basement rocks are predominantly composed of granitoids.
