The crater is estimated 90km (55.9mi) in diameter and is estimated to have occurred about 580 million years ago. The large size estimate would imply an energy release on par with 5.2 x 106 megatons of TNT.

Evidence of a huge collision can be found as far as 300km (186.4mi) east of the crater. Now that's really interesting and wonderful..
