Magnitude is a measure of earthquake size and remains unchanged with distance from the earthquake. Intensity, however, describes the degree of shaking caused by an earthquake at a given place and decreases with distance from the earthquake epicentre. How Does Earthquake Magnitude Differ from Intensity? Earthquakes can have a devastating impact on communities, and it […]Types of Magnitudes Magnitude is expressed in whole numbers and decimal fractions. For example, a magnitude 5.3 is a moderate earthquake, and a 6.3 is a strong earthquake. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude as measured on a seismogram.2016. 8. 26. ...

Intensity is a measurement of how much shaking has occurred as measured by levels of observable destruction of man-made and natural objects. The magnitude that is measured does not vary with distance from the epicenter. Magnitude and intensity are terms used in different contexts: magnitude is the size or quantity of something, such as the strength of an earthquake, while intensity is the subjective effects or impact of an event, such as the level of damage caused by an earthquake.How does it compare with a magnitude 3 quake? The amplitude of the largest seismic wave of a magnitude 5 quake is 10 times that of a magnitude 4 quake and 100 times that of a magnitude 3 quake. Each scale has their benefits. As mentioned above, the Mercalli Intensity scale is based on how much damage someone would see.. We do not try using the same depth ranges for different data sQuestion: How do the intensities of a magnitude 6.0 However, since the Energy Magnitude and Moment Magnitude measure two different properties of the earthquake, their values are not the same. The energy release can also be roughly estimated by converting the moment magnitude, M w, to energy using the equation log E = 5.24 + 1.44M w, where M w is the moment magnitude. IntensityThe magnitude of earthquake is determined from measurements on seismographs, whereas the intensity is determined from effects on people, human structures, and the natural environment. Table 1 presents the difference between magnitude and intensity of earthquake. Monitoring Earthquakes. We monitor earthquakes by measuring th Earthquake magnitude and intensity are both important measurements obtained after an earthquake. They refer to two different aspects of the seismic event, the size and the damage, but they are often confused with one another. The magnitude is a number indicating the size of the seismic event. An earthquake has only one value of magnitude. The shaking and damage caused by an earthquake is termed ...
