Date:March 19, 2001 Source: Stanford University
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).
