   Summary:Elephant researchers have discovered that there is more to a   
   mock charge than meets the eye - or the ear, for that matter. It turns   
   out that foot stomping and low-frequency rumbling also generate   
   seismic waves in the ground that can travel nearly 20 miles along the   
   surface of the Earth, according to a new study in the Journal of the   
   Acoustical Society of America (JASA).
