Elephants Use Ground Vibrations to Communicate Over 10 km

Elephants are capable of long‑range communication using both airborne and ground‑based signals. While they can transmit vocalizations that travel up to five kilometres (three miles) through the air, they also employ a second, more distant method: seismic waves generated by the impact of their feet.

These ground vibrations travel through the earth, are picked up by the elephants’ legs, and then transmitted through the bones of the skull directly into the inner ear—a process known as bone‑conduction hearing. This mechanism allows elephants to perceive signals over distances of ten kilometres (six miles) or more, far exceeding the range of their vocal communications.

The discovery of bone‑conduction hearing in elephants highlights the complexity of their sensory world and provides insight into how these large mammals maintain social cohesion across vast savannah landscapes.
