LOL…I know that Eighty just pulling your leg there. I didn’t quite fully understand your question as stated. Corrie, that’s a good link but I would think that an underwater explosion isn’t all that different except that you would have plenty of water displacement together with plenty of air bubbles.  Here are some underwater explosion scenes I gathered from the Internet. Some of these show underwater volcanic activity which may or may not be viewed as actual explosions. The bottom last scene is a game frame capture from “Silent Hunter” by UBISOFT used here purely for illustration.
