It looks like a black crater to me. Others here are welcome to comment.
Then you have never seen craters, apparently.

If the red circle is the area that you believe is a crater, then please take note of the two lines I added here; the first is the green line, which shows what appears to be vegetation behind the parking area. That vegetation shows no signs of being disturbed by any blast. The second, the blue line, denotes the line of cars parked along that row. Those cars seem remarkably unaffected by the force of a missile striking only a few feet behind them.
This is not a crater. Thanks for playing, please try again.
