  I remember an interesting patch on an old modular that would simulate
both thunder and explosions. It may give you a starting point... It used
fours oscillators tuned to different subsonic frequencies... what was
actually heard were the beat frequencies of the differently-tuned
oscillators. Of course
it may have been the eighteen-inch Cerwin-Vega's I was using that made
it so realistic...

few years back I had a friend stay up all night whacking a thousand gallon
cement hopper with a twenty pound steel pipe. eventually got a whack i
liked with a nice sustained fade. then layered it with about 40 variously
pitch shifted variously delayed lines on a four track porta studio. sounded
just like those factory explosions over in new jersey. try delay lines
closer together a couple hundred milliseconds after attack for a rapid
crescendo and add some reverb (p104 manual). no problem for c-soundIn but
would you like me to see if whacker is still available?
