If it has a "whooshh-bang" explosion, those are what I call "yin and yang" explosions, or "BnW Pokeman" explosions, since the white is usually swirled with black, like the yin yang symbol. My guess is that those are caused when a projectile of some form hits at a location that does not have a damage sphere associated with it. A LOT of the DD and smaller craft in the game are not completely set-up with them... think of it as the "default" explosion in those cases. They really should be the "background" image, and not in the fore...
