_{Did you know?An earthquake’s strength can be measured in a variety of ways; the two most common methods are intensity and magnitude. Earthquake intensity is a measurement of the surface damage resulting from an earthquake. It is most commonly measured with the Mercalli scale as seen in Figure 10. 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.The magnitude of an earthquake is determined by taking the logarithm (in base 10) of the greatest movement of the soil recorded during the arrival of a type ...Earthquakes can be measured in two ways.
