Nukes also have a distinct and easily identifiable P and S Wave pattern. It's how we know that China and the USSR popped at least one nuke off in their border wars back in the 70s.
Or a tiny nuke?

Nah. Richter 2 point something was several tons TNT equivalent when "Kursk" blew up - and there are no micro-nukes with that kind of yield. There are a few in subkiloton range, but that would be 100 times more powerful - i.e. Richter 4 point something.
