... increasing distances from an earthquake indicate that seismic velocities gradually increase with depth in the mantle (exceptions: see Low Velocity Zone and 670 km Discontinuity above). However, at arc distances of between about 103° and 143° no P waves are recorded. Furthermore, no S waves are recor ...

Seismic communication
Seismic communication, sometimes called vibrational communication, describes the conveying of information through seismic vibrations of the substrate. The substrate may be the earth, a plant stem or leaf, the surface of a body of water, a spider’s web, a honeycomb, or any of the myriad types of soil substrates. Seismic cues are generally conveyed by Rayleigh waves generated through vibrations on the substrate, or acoustical waves that couple with the substrate. Vibrational communication is an ancient sensory modality and it is widespread in the animal kingdom where it has evolved several times independently. It has been reported in mammals, birds, reptiles, amphibians, insects, arachnids, crustaceans and nematode worms. Vibrations and other communication channels are not necessarily mutually exclusive, but can be used in multi-modal communication.
