Earth: Iowa impact crater confirmed

10 July 2013—Scientists have recently confirmed the existence of an impact crater buried below the town of Decorah, Iowa. Scientists first discovered what they thought resembled a crater in 2008, but now it has been corroborated by an airborne geophysical survey. Scientists estimate the diameter of the crater at 5.5 km-wide, nearly five times the size of the Barringer Meteor Crater in Arizona.

Based on the crater's size, scientists calculate that the region was likely hit by a meteorite roughly 250-m in diameter about 500 million years ago, and could be related to other Midwestern impact craters. Statistically, similar-sized impactors could hit Earth's surface every 30,000 to 60,000 years.
