The difference between these two magnitudes is... A magnitude earthquake is times bigger than a magnitude earthquake, but it is times stronger (energy release). USGS Earthquake Hazards Program, responsible for monitoring, reporting, and researching earthquakes and earthquake hazards Following your example, if your earthquake is very shallow you would have a huge magnitude difference between your station at distance d and the epicenter, whereas if the hypocenter is 600 km deep, m will be very similar in both places. So you need to know the depth of the earthquake to derive the magnitude in the epicenter.The magnitude of an earthquake is a number that allows earthquakes to be compared with each other in terms of their relative power. For several decades, earthquake magnitudes were calculated based on a method first developed by Charles Richter, a seismologist based in California. v t e Seismic magnitude scales are used to describe the overall strength or "size" of an earthquake. These are distinguished from seismic intensity scales that categorize the intensity or severity of ground shaking (quaking) caused by an earthquake at a given location.Nov 20, 2020 · To compare two earthquakes in terms of shaking, you subtract one magnitude from the other and raise 10 to that power: 10^(M1-M2). For example, if the magnitude of one quake is 6 and another is 4, than the difference in magnitudes is 2, so the stronger earthquake shakes 10^2 or 100 times as hard as the milder one.

The Richter magnitude is based on a scale of 10, with the magnitudes starting from a less than 2.0 reading to a 10+ reading, though the latter has never been recorded. The readings help to arrive at the level of magnitude of an earthquake, from micro and light to strong and great, though after taking into account the earthquake intensity as well.
