Shiva crater
The Shiva Crater is located in the Indian Ocean west of India. It was formed around 65 Million years ago, the same time as a number of other impacts that are recorded in the K-T boundary.
The Deccan Traps are located in the theorized center of the crater, lending support to the idea that the traps were created by the impact event.
The crater is believed to be 600km long and 400km wide.
