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. It is calculated by measuring the magnitude of the seismic influence (for a Seismometer). The scale that is used to the measure extent of an earthquake ...The Richter scale measures the magnitude of an earthquake's largest jolt of energy. This is determined by using the height of the waves recorded on a seismograph. The Richter scale is logarithmic. The magnitudes jump from one level to the next. The height of the largest wave increases 10 times with each level.

Two key parameters used to describe earthquakes are magnitude and intensity. Understanding the difference between these two measures is important in developing effective strategies for mitigating the threat posed by earthquakes. Magnitude is a measure of the size or energy released by an earthquake.So the intensity of an earthquake will vary depending on where you are. Sometimes earthquakes are referred to by the maximum intensity they produce. Magnitude scales, like the Richter magnitude and moment magnitude, measure the size of the earthquake at its source. So they do not depend on where the measurement is made. Often, several slightly ...Another way of looking at the size of earthquakes is to figure out how much energy they release. Some rules of thumb have been found to compare magnitude to energy, and it has been found that for each one point magnitude increase (say from a 4 to a 5), 32 times as much energy is released. If one jumps from a 5 to a 8, the energy goes up by 32 x ...Intensity is a more subjective (qualitative) measure of an earthquake’s strength that is based on the kind of damage the earthquake produced an the people’s reaction to the …Tohoku-oki Earthquake animation featured in National Geographic Video.
