As E A r e a ↓, the amplitude decreases with distance.Earthquake magnitude and intensity are both important measurements obtained after an earthquake. They refer to two different aspects of the seismic event, the size and the damage, but they are often confused with one another. The magnitude is a number indicating the size of the seismic event. An earthquake has only one value of magnitude.2. The moment magnitude depends on: (a) the amount of slip on the fault plane (b) the area of the fault break (c) rigidity or strength of the rock. 3. The total energy of an earthquake can be related to its Richter magnitude using the following equation: log E = A + BM. E = total energy in ergs. A and B are constants which depend on local geology(There are two measures of energy released (magnitude) by an earthquake: Richter magnitude and moment magnitude. The Richter magnitude is an estimate of energy release made from the amplitude of seismic waves recorded on a seismograph at a known distance from the epicenter (distance known by the difference in arrival times of P and S waves).You can measure an earthquake either by its size where the rock slipped, or by the amount of shaking that is experienced at a place that interests you.
