The transfer of energy in an earthquake
... When an earthquake occurs energy is transferred, from where the rocks break, and travels throughout the world. The bigger the quake the further from the epicentre the waves will travel. There are two types of earthquake wave generated during an earth quake. They carry energy away from the earthquake ...

Temperatures and tectonic history of the North American continent
... Background: There are many open questions about the internal structure of the continental plates that we live on, and what this structure tells us about how continents are formed. For example, why are old continental cores impervious to the type of recycling that happens to oceanic lithosphere? Is t ...

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.
