Magnitudes are usually determined from measurements of an earthquake's …This scale measures the magnitude of an earthquake. It is measured using a machine called a seismometer , which produces a seismograph. The Richter scale is normally numbered 1-10.The Indian Ocean Earthquake that struck the coast of Indonesia in 2004 was registered as a 9.0 magnitude earthquake. Magnitude is a measurement of the energy released from an earthquake and is measured on a Richter scale, usually with a reading between 2 and 9. Earthquakes of magnitude 8.0 or greater are very rare and can completely destroy ...Measuring Magnitude; Measuring Earthquakes; Physics shows us that energy is always transmitted in waves. Every wave has a high point called a crest and a low point called a trough.The height of a wave from the center line to its crest is its amplitude.The distance between waves from crest to crest (or trough to trough) is its wavelength.. The energy …

Magnitude is an estimate of the relative "size" or strength of an earthquake, and thus its potential for causing ground-shaking. It is "approximately related to the released seismic …

In an earthquake, damage to buildings and infrastructure is related more closely to ground motion, of which PGA is a measure, rather than the magnitude of the earthquake itself. For moderate earthquakes, PGA is a reasonably good determinant of damage; in severe earthquakes, damage is more often correlated with peak ground velocity. Magnitude. The magnitude of an earthquake is a measure of the total amount of energy released by the ground movement at its source. It is commonly determined by analysing the shaking recorded on several seismographs. The shaking movement, or ground acceleration, causes the trace on the seismograph to deflect up and down with time.– The common earthquake Richter Scale is a measure of how much ground movement a local earthquake produces. For example, an R=5.0 earthquake produces 10 times more ground movement than an R=4.0 earthquake. This scale is calibrated so that an R=0 earthquake at a distance of 100 km produces a ground change of 1 micron (10A better measure of the size of an earthquake is the amount of energy released by the earthquake, which is related to the Richter Scale by the following equation: Log E = 11.8 + 1.5 M (where Log refers to the logarithm to the base 10, E is the energy released in ergs and M the Richter magnitude).
