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 kilometres (1.9 mi),[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]
