Paleoseismology — looks at geologic sediments and rocks, for signs of ancient earthquakes. It is used to supplement seismic monitoring, for the calculation of seismic hazard. Paleoseismology is usually restricted to geologic regimes that have undergone continuous… … Wikipedia

Soil liquefaction — describes the behavior of loose saturated unconsolidated soils, i.e. loose sands, which go from a solid state to have the consistency of a heavy liquid, or reach a liquefied state as a consequence of increasing porewater pressures, and thus… … Wikipedia

Seismology — (from Greek gr. σεισμός, seismos , earthquake ; and gr. λογία, logia ) is the scientific study of earthquakes and the propagation of elastic waves through the Earth. The field also includes studies of earthquake effects, such as tsunamis as well… … Wikipedia
Seismic hazard — refers to the study of expected earthquake ground motions at the earth s surface, and its likely effects on existing natural conditions and man made structures for public safety considerations; the results of such studies are published as seismic … Wikipedia

Characteristic earthquakes — Almost all geology is fractal and scale invariant. That means you should always put in a scale when taking pictures of rock formations. For example, in this picture, you can’t tell if it is 6 m or 6 km across. It’s actually an ASTER satellite… … Wikipedia
