What is the scale used to measure earthquakes.
The moment magnitude scale (Mw) is a logarithmic scale used to measure the size of earthquakes. It is based on the seismic moment, which is a measure of the energy released by an earthquake. The seismic moment is calculated by multiplying the area of the fault that ruptured by the average amount of slip and the rigidity of the rock.

There are two primary scales used to measure earthquakes: the Richter scale and the Mercalli scale. The Richter scale is most common in the United States, while worldwide, scientists rely on the Mercalli scale. The moment magnitude scale is another earthquake measurement scale used by some seismologists.
Richter’s scale was originally for measuring the magnitude of earthquakes from magnitudes 3 to 7, limiting its usefulness. Today the moment magnitude scale, a closer measure of an earthquake’s total energy release, is preferred.

Seismometers record the vibrations from earthquakes that travel through the Earth. Each seismometer records the shaking of the ground directly beneath it.
The Moment Magnitude Scale. The Moment Magnitude Scale measures the amount of energy released by an earthquake event. It is calculated using a formula that includes the rigidity of the rock affected, the distance moved and the size of the area where movement takes place. The video on the left below explains this more fully.
