Updated Oct 3, 2023 | 04:49 PM IST EarthQuake KEY HIGHLIGHTS The Moment Magnitude Scale has replaced the Richter scale for its global applicability and accuracy in measuring large earthquakes. The Mercalli scale provides a human perspective by measuring earthquakes based on observed damages.The Richter Magnitude scale is one such scale that you have likely heard of. Figure 6.2. 1: Seismogram. One issue with measuring earthquakes is that as the waves propagate, the energy is spread out over more area. Figure 6.2. 2: Distance from Source. As E A r e a ↓, the amplitude decreases with distance.The moment magnitude scale is based on the total moment release of the earthquake. Moment is a product of the distance a fault moved and the force required to move it. It is derived from modeling recordings of the earthquake at multiple stations. Moment magnitude estimates are about the same as Richter magnitudes for small to large earthquakes.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.

Richter Scale. Magnitude is the measure of the energy released by an earthquake. The Richter scale (M L), the first and most well-known magnitude scale, was developed by Charles F. Richter (1900-1985) at the California Institute of Technology. This was the magnitude scale used historically by early seismologists.
The magnitude scale is logarithmic. That just means that if you add 1 to an earthquake's magnitude, you multiply the shaking by 10. 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.With a magnitude of 6.8, it is categorized as "strong" on the magnitude scale.
