I think vibration only calls for oscillation.  Webster has the following to
say:

   1 a : a periodic motion of the particles of an elastic body or
         medium in alternately opposite directions from the position
         of equilibrium when that equilibrium has been disturbed (as
         when a stretched cord produces musical tones or molecules in
         the air transmit sounds to the ear)

So, I guess, technically, the world isn't vibrating, although certain days
it definately seems to have a kind of hum... ;)
