Learn more: USGS Geomagnetism Program. No, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs. That is, the longer the fault, the larger the earthquake. A fault is a break in the rocks that make up the Earth's crust, along which rocks on either side have ...
Magnitude scales do not used express damage and nor do they provide a direct indication of the shaking level on the ground surface. However, Intensity scales, like the Modified Mercalli Intensity Scale or the Japan Meteorological Agency’s Seismic Intensity Scale, do provide an indication of the extent and distribution of the damage caused from ground surface shaking caused by an earthquake.

Vast swaths of the region was hit by less severe shaking. (USGS)It does not have a mathematical basis; instead it is an arbitrary ranking based on observed effects. 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.
Sep 29, 2023 · Enter the two magnitudes you want to compare – for our example, these are 5.8 and 7.1. We find out that a magnitude of 7.1 is 20 times bigger (on a seismogram, in terms of amplitudes) and ~89 times stronger (in terms of energy release) than a 5.8 magnitude. Remember that for each unit increase in magnitude:

However, in measuring the seismic moment, the Chilean quake was larger, giving M w of 9.5 versus the M w of 9.2 for the Alaskan earthquake. The reason is that the Chilean earthquake released more energy, but in the Alaskan ... The 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. Earthquakes of magnitude 5.0 cause light damage near the epicentre; those of 6.0 are destructive over a restricted area; and those of 7.5 are at the lower limit of major earthquakes. The total annual energy released in all earthquakes is about 10 25 ergs, corresponding to a rate of work between 10 million and 100 million kilowatts. Dec 2, 2022 · 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.
