To scientists, an earthquake is an event inside the earth. To the rest of us, it is an extraordinary movement of the ground. Magnitude measures the former, while intensity measures the latter.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.Earthquake magnitudes are determined from seismic waves, the ground-bending waves generated by the earthquake fault. The energy in these waves lessens with distance. As you move farther from the earthquake fault, the intensity of the shaking decreases.
