NettetEarthquakes are rupturing processes in the Earth's crust that lead to vibrations on the surface layer of the planet. Most of the damaging earthquakes so far have been tectonic in origin (tectonic quakes). They are caused by a sudden displacement along a fracture face in the Earth's crust and by the resulting release of accumulated elastic energy.

Seismic intensity scales categorize the intensity or severity of ground shaking (quaking) at a given location, such as resulting from an earthquake. They are distinguished from seismic magnitude scales, which measure the magnitude or overall strength of an earthquake, which may, or perhaps may not, cause perceptible shaking. Intensity scales are based on the observed effects of the shaking, such as the degree to which … NettetThere are a lot of equations, developped by several authors, relating the energy released by an earthquake as seismic waves and the magnitude. One of the first appeared in …

NettetFor example, a magnitude 6.0 earthquake releases about 32 times as much energy as a magnitude 5.0 earthquake. A magnitude 7.0 releases about 32 × 32 = 1024 times as much energy as a magnitude 5.0 earthquake. A magnitude 9.0 earthquake, which rarely occurs, releases over a million times as much energy as a magnitude 5.0 earthquake. NettetFor example, during the 1964 Prince William Sound, Alaska, earthquake, more than 200 bridges were damaged or destroyed by lateral spreading of flood-plain deposits toward river channels. These spreading deposits compressed bridges over the channels, buckled decks, thrust sedimentary beds over abutments, and shifted and tilted abutments and …
