2nd link would be the closest but not, the right time. there was definately acoustic energy, in the air, this wasnt ground tremor, it was distinctly different, and the volume followed the appearance, zenith, and dissapearance of the spiral. it was not a snowquake either, and it wasnt from Clear, or Elmo.
