Distance from the epicenter. Depth to the hypocenter. Local rock and soil conditions. Module 1—Effect of magnitude on intensity of ground shaking. The magnitude, or size, of an earthquake is related to the total amount of energy released by the earthquake source. 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. Both measures are used.

Measures the total energy released by an earthquake. Moment magnitude is calculated from the area of the fault that is ruptured and the distance ... To locate an earthquake epicenter: 1. Scientists first determine the epicenter distance from three different seismographs. The longer the time between the arrival of the P-wave and S-wave, the farther away is the epicenter. So the difference in the P and S wave arrival times determines the distance between the epicenter and a seismometer. The MMI scale is a seismic scale used for measuring the intensity of an earthquake. ... Many people do not recognize it as an earthquake. Standing motor cars may ...
