How an earthquake is measured.
No matter what scale is used, quakes are detected using devices called seismographs, which measure ground motion and produce images showing how these vibrations travel over time. The magnitude of a quake determines how it is classified by organizations such as the U.S. Geological Survey, from "micro" quakes—the smallest that can be felt ...

A 4.2-magnitude earthquake was measured roughly 2.5 miles south-southwest of Isleton on Wednesday morning. Read our full coverage: Expand All. …Earthquake magnitudes are determined from seismic waves, the ground-bending waves generated by the earthquake fault. The energy in these waves lessens with distance. As you move farther from the earthquake fault, the intensity of the shaking decreases. At a fixed distance from the fault, the larger the earthquake magnitude, the greater the shaking.Moment magnitude scale. The moment magnitude scale ( MMS; denoted explicitly with Mw or Mw, and generally implied with use of a single M for magnitude [1]) is a measure of an earthquake 's magnitude ("size" or strength) based on its seismic moment. It was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori.An earthquake’s most intense shaking is often felt near the epicenter. However, the vibrations from an earthquake can still be felt and detected hundreds, or even thousands of miles away from the epicenter. How Do We Measure Earthquakes? The energy from an earthquake travels through Earth in vibrations called seismic waves. Scientists can ...Fast Fact: Measuring Earthquakes.

Earthquake - Magnitude, Intensity, Effects: The violence of seismic shaking varies considerably over a single affected area. Because the entire range of observed effects is not capable of simple quantitative definition, the strength of the shaking is commonly estimated by reference to intensity scales that describe the effects in qualitative terms. Intensity scales date from the late 19th and ...A 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).
