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. Both measures are used. The measure of the size of the earthquake where it occurred is the “magnitude.”. Each earthquake has a single value on a magnitude scale – the strength right in the ...Earthquake intensity scales describe the severity of an earthquake's effects on the Earth's surface, humans, and buildings at different locations in the area of the epicenter. There can be multiple intensity measurements. The Modified Mercalli Scale measures the amount of shaking at a particular location. Earthquake Magnitude Scale

Even for distant earthquakes, measuring the duration of the shaking (as well as the amplitude) provides a better measure of the earthquake's total energy. Measurement of duration is incorporated in some modern scales, such as M wpd and mB c . M c scales usually measure the duration or amplitude of a part of the seismic wave, the coda. Magnitude scales, like the moment magnitude, measure the size of the earthquake at its source. An earthquake has one magnitude. The magnitude does not depend on where the measurement is made. Often, several slightly different magnitudes are reported for an earthquake.The Richter Scale is a logarithmic scale for measuring earthquakes, meaning a 5 is ten times more powerful than a 4.
