Crater Chains
NASA - In Search of Crater Chains
In a remote windswept area named Aorounga, in Chad, there are three craters in a row, each about 10 km in diameter. "We believe this is a 'crater chain' formed by the impact of a fragmented comet or asteroid about 400 million years ago in the Late Devonian period," explains Adriana Ocampo of NASA headquarters.I've been meaning to blog this for a while - ever since Emilio González used Google Earth to find some previously unknown meteorite impact craters.
Now it has been possibly confirmed as a crater chain that ties together the Aorounga and Kebira impact craters - although it needs ground research to confirm.
Strangely enough - all around the area where the impact craters are located are other circular structures that look like extinct volcanoes - maybe that is why this recent addition went up on the Astroseti website.
Now that everyone seems to be reporting structures, please, independently of using NASA World Wind, Google Maps, Google Earth, etc., please if you think you have discovered anything use Google Earth (download it if it is not yet installed in your computer) and turn Google Earth Community layer on. This is the first thing to see if anyone else found that structure before. Later using NASA World Wind for verifying is great. With different layers maybe you can appreciate more details, and the 3D view can be helpful.
Please don't bother geologists with anything that looks like a circle
