Elephants communicate using low rumbling sounds that travel long distances through the ground.

The longer version

Elephant rumbles sit at such a low pitch that much of the sound falls below the range human ears detect. Low frequencies travel farther than high ones because they scatter less off vegetation, soil and warm air, so the call carries across savannah far better than a shout would.

The vibrations also pass into the ground and spread through it as seismic waves. An elephant appears to pick up these signals through its feet and trunk, where sensitive nerve endings respond to the shaking. Relatives several kilometres away can therefore register a greeting, a warning, or a reproductive signal long before any visible contact.
