This ring is kept in place by two opposing forces: the centripetal force due to the earth's rotation and a counteracting pressure gradient force. If some disturbance, such as an earthquake, perturbs the ring, moving it away from its stable position, the centripetal and pressure forces will play against one another to return the ring to its original position.
