This moment can be related to a corresponding magnitude for easier interpretation, called the moment magnitude. The benefit of this type of measurement is that ...
The moment magnitude scale (MMS) was devised by scientists after the 1960 Chilean earthquake and the 1964 Alaskan earthquake. These great subduction zone earthquakes broke along fault lines that were hundred of kilometers long. The moment magnitude scale in determining an earthquake's magnitude takes in "the entire moment" of the earthquake.The magnitude is based on the seismic moment of the earthquake, which is equal to the rigidity of the Earth multiplied by the average amount of slip on the fault and the size of the area that slipped. The scale was developed in the 1970s to succeed the 1930s-era Richter magnitude scale (ML).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 · If you're listening to the news about an earthquake, the measure that will be given is the magnitude — the moment magnitude to be exact. Nowadays, the moment magnitude scale is the most commonly used system. The strongest earthquake ever recorded – the one in Chile in 1960 — was 8.6 on the Richter magnitude scale but had a moment ...

Both scales are used in tandem because the estimates of magnitude may change after a quake. The Richter scale is used as a quick determination immediately following the quake (and is usually reported in news accounts), and the moment magnitude is calculated days to months later.

The moment can be estimated from seismogram s (and also from geodetic measurements). The moment is then converted into a number similar to other earthquake magnitudes by a standard formula. The result is called the moment magnitude. This scale rates an earthquake according to how much damage it causes. This scale produces a single rating for earthquakes that reach the surface. This scale measures the magnitude of an earthquake based on the size of seismic waves.
