This's a Joel Valentine sound effect.
It is NOT to be confused with any of the Hanna-Barbera/Universal Studios explosions, even though Joel Valentine tends to use higher-quality, processed and/or modified versions of that infamous "POH-WAHH-WAHHHHH!" sound, but it may or not maybe similar to/includes SKYWALKER EXPLOSION 01.
It might've been the same sound effect as Sound Ideas, Explosion Single Large 11 - Single, large explosion with fiery ending, which can be found on the Sony Pictures Sound Effects Library Volumes 6-10.
