🕑 Reading time: 1 minute Magnitude and intensity measure various characteristics of earthquake. The former measures the energy released at the source of the earthquake. However, the latter measures the strength of shaking generated by the earthquake at a certain location. The magnitude of earthquake is determined from measurements on seismographs, whereas the intensity is determined […] Seismic intensity is controlled by four main factors: Magnitude. 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.The Intensity Prediction Equation (IPE) is an estimate of intensity for a given earthquake magnitude and distance. Earthquakes in different regions of the world tend to create different levels of shaking for many reasons, such as the mechanism of the earthquake, the nature of the geological environment, and the quality of infrastructure.
