... b. Most earthquakes have magnitudes too SMALL to be felt by humans—3.0 to 4.9 on the Richter scale. 3. The modified MERCALLI intensity scale describes earthquake intensity based on structural and geologic damage. 4. LIQUIFACTION shaking from an earthquake can make wet soil act like a liquid. 5.

... Surface Waves • Develop when seismic waves reach the earth’s surface. • Move more slowly than P waves or S waves. • Produce larger ground movements and greater damage. • Some are transverse, others are similar to ocean waves. ...

... This theory states --- sudden return of elastically deformed rock to its undeformed shape. If the fault is locked, stress increases. When stress reaches passed a certain point, the rocks fracture, separate at weakest point, and spring back or rebound, to original shape. As they fracture and slip the ...

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.
