The magnitude of an earthquake is a measure of the energy it releases. This means that it doesn't matter that the earthquake might not "feel" as strong farther away from its source; the magnitude just depends on the earthquake's total energy. The more energy released by an earthquake, the higher the magnitude.For instance, an earthquake of magnitude 6.0 releases approximately 32 times more energy than a 5.0 magnitude earthquake and a 7.0 magnitude earthquake releases 1,000 times more energy than a 5.0 magnitude earthquake.

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 ...Energy released for each whole number measurement is about 31 times greater than that released by the whole number before. So, for example, a magnitude 2 earthquake is 31 times more powerful than a magnitude 1 earthquake. The moment magnitude scale is often referred to by the name of its predecessor, the Richter Scale.The Modified Mercalli Intensity value assigned to a specific site after an earthquake has a more meaningful measure of severity to the nonscientist than the magnitude because intensity refers to the effects actually experienced at that place. ... The intensity of an earthquake at a location is a number that characterizes the severity of ground ...The magnitude of an earthquake is a number that characterizes the relative size or amount of elastic energy released by such an event (see “Earthquakes, Energy”).It is usually based on measurement of the maximum ground motion recorded by a seismograph (sometimes for a particular wave type and frequency) and corrected for the decay of amplitudes with epicentral distance and source depth due ...You can measure an earthquake either by its size where the rock slipped, or by the amount of shaking that is experienced at a place that interests you.
