Similar to intensity scales, over the years, a number of approaches for measurement of magnitude of an earthquake have come into existence. 4.7 Calculation of Earthquake Magnitude and Intensity 1. Richter Magnitude, M A workable definition of magnitude was first proposed by C.FMagnitude. A familiar analogy to help understand earthquake size metrics is to think about a light bulb. One measure of the strength of a light bulb is how much energy it uses. A 100-watt bulb is brighter than a 50-watt bulb, but not nearly as bright as a 250-watt bulb. The wattage of a bulb tells you about the strength of the light source.A common example of intensity is the decibel scale for sound. This scale measures the loudness of sound on a scale of 0 to 140 decibels. The louder the sound, the higher its intensity. Magnitude vs Intensity in Physics. In physics, magnitude and intensity are often used to describe different aspects of the same phenomenon.Luminosity, in astronomy, the amount of light emitted by an object in a unit of time. The luminosity of the Sun is 3.846 × 1026 watts (or 3.846 × 1033 ergs per second). Luminosity is an absolute measure of radiant power; that is, its value is independent of an observer’s distance from an object.The irradiance (or intensity) is the magnitude of the time average of the Poynting vector: Since the time-dependence of S is given by a cos2, we must take the time average of this function. 22 (,) cos( ) 00 Srt c E B k r t The average of cos2(x) is ½:Diabetes impacts the lives of more than 34 million Americans, which adds up to more than 10% of the population.

The Modified Mercalli intensity scale ( MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth.

The magnitude of an earthquake is a value that tells an onlooker the amount of seismic energy released by this. It is a single value and does not depend on the distance from the epicenter.

The moment magnitude scale is often referred to by the name of its predecessor, the Richter Scale. Measurements on the Modified Mercalli Intensity (MMI) scale range from I to XII and are based solely on damage assessment and eyewitness accounts. If m1 and m2 are the magnitudes of two stars, then we can calculate the ratio of their brightness ( b 2 b 1) using this equation: m 1 − m 2 = 2.5 log ( b 2 b 1) or b 2 b 1 = 2.5 m 1 − m 2. Here is another way to write this equation: b 2 b 1 = ( 100 0.2) m 1 − m 2. Let’s do a real example, just to show how this works.
