What Are the Odds?!?

I got in to work this morning and found that overnight, one of my tanks
bottom glass "gave out".

I didnt realise what had happened right away...

I had assumed that the bottom seal gave out so naturally I took everything
out and was going to re-seal the tank.

I was amazed when I got to the bottom and saw the tempered glass was
shattered!

Has this happened to anyone else before?

Tempered glass under stress can be shattered by vibration, I think the
culprit is low frequency. At least the examples I know of (none of which
have been tanks) have been associated with things like heavy lorries going
past.

Oh great! What about the idiots with the 6 foot bass speakers in their
cars? We've got one that goes by every night about 5pm.

I had a friend whose front panael on his tank smashed after a heavy truck
went past. He was watching the tank as it happened and claimed to see tiny
ripples on the surface of the water just before it exploded.

You're probably OK with any music system. The bass bin might be able to
cope, but CD and tape simply can't produce the really low frequencies.

Hmm.. I live too close to an Air Force base. They fly A-10's over my
house every day. I think something in their comm system turns on my X10
remote control lamp. Should I be prepared for a disaster?
HOW do you prepare for such a thing?
