Could these be the waves from an underwater explosion? Found in a lagoon in Acapulco, the circular waves could be caused by any number of different events.
However, the waves are about 8m peak to peak, and still can be clearly seen 400m to the South East, implying that this is more than simply someone jumping in the water!
On the Google Earth forum it has been suggested this may be the result of a small earthquake, or perhaps an underwater explosion to remove reef rock below.
I think the explosion idea holds more weight, but it still seems unlikely. Is there anyone more qualified on such matters who can answer either way? Or at least someone out there with a wild conspiracy theory?
