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 […] 4.3 Measuring and Locating Earthquakes Focus and Epicenter. The focus, also called a hypocenter of an earthquake, is the point of initial breaking or rupturing where the displacement of rocks occurs. The focus is always at some depth below the ground surface in the crust and not at the surface. Oct 18, 2023 · On the Richter scale, the Alaska quake was "bigger" having a M S of 8.6 compared to the M S of the Chilean quake of 8.5. However, in measuring the seismic moment, the Chilean quake was larger, giving M w of 9.5 versus the M w of 9.2 for the Alaskan earthquake. The reason is that the Chilean earthquake released more energy, but in the Alaskan ... Although often confused, they each measure different characteristics of an earthquake. Magnitude measures the amount of seismic energy released at the source - or hypocenter - of an earthquake. An earthquake has only one magnitude determined from measurements on seismographs.
