Right everyone, it is time to reveal the answer to all of you. First of all I would like to thank all of you who participated, your guesses were great 🙂
This is simply a fraction of the Decan Traps in India, they were created by extremely violent volcanic activity that shook the area millions of years ago, around the era when the Dinosaurs went extinct. Hence the confusion whether it was an asteroid or the Decan Traps that caused the extinction event.
A lot of you came really close to unveiling the answer, some said Australia and others said Africa, very close! 🙂
Now here is a photo of the area from a different perspective, enjoy! 🙂
