The quake …An earthquake of magnitude 5 shakes 10 times as violently as an earthquake of magnitude 4; a magnitude-6 quake shakes 10 times as hard as a magnitude-5 quake; and so on. To compare two earthquakes in terms of shaking, you subtract one magnitude from the other and raise 10 to that power: 10^(M1-M2). Use it as the earthquakes' magnitude calculator to compare two earthquakes' magnitudes. ...The three primary scales used to describe the size of earthquakes are the Richter Magnitude Scale, Modified Mercalli Intensity Scale, and Moment Magnitude ...Comparison between measurements on the Modified Mercalli scale and magnitudes on the moment magnitude scale. Earthquakes can be measured in two ways. One method is based on magnitude—the amount of energy released at the earthquake source. The other is based on intensity—how much the ground shakes at a specific location. The following table provides a comparison between earthquake intensity levels as measured by the Mercalli scale and their approximate magnitude on the Richter scale. The Mercalli scale is based on observed effects of an earthquake, while the Richter scale measures the amount of energy released during an earthquake. Intensity (Mercalli ...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. 7. feb 2023. ...
