Magnitude measures the energy released at the source of the earthquake. Magnitude is determined from measurements on seismographs. Intensity measures the strength of shaking produced by the earthquake at a certain location.Enter the two magnitudes you want to compare – for our example, these are 5.8 and 7.1. We find out that a magnitude of 7.1 is 20 times bigger (on a seismogram, in terms of amplitudes) and ~89 times stronger (in terms of energy release) than a 5.8 magnitude. Remember that for each unit increase in magnitude:The duration of an earthquake is related to its magnitude but not in a perfectly strict sense. There are two ways to think about the duration of an earthquake. The first is the length of time it takes for the fault to rupture and the second is the length of time shaking is felt at any given point (e.g. when someone says "I felt it shake for 10 seconds" they are making a statement about the ...The energy of an earthquake can be calculated from the moment magnitude scale value alone. Two earthquakes of different duration, but the same moment magnitude, have the same energy. The destructive effect of an earthquake is described by the intensity, and a scale such as the Mercalli Intensity scale.The Modified Mercalli intensity scale ( MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth.

Earthquakes are measured with the Richter Magnitude Scale developed by Charles F. Richter of California Institute of Technology in 1935.

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 ...

READ: Top 5 most destructive earthquakes in the ...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.Jul 22, 2020 · Seismographic networks measure earthquakes by their magnitude, energy release and intensity. Years ago, all magnitude scales were based on the recorded waveform lengths or the length of a seismic wave from one peak to the next. But for very large earthquakes, some magnitudes underestimated the true earthquake size. With this series of 2-minute animations, called “Myth-Conceptions”, we address common misunderstandings, misconceptions and myths about Earth science topics.Magnitude scales do not used express damage and nor do they provide a direct indication of the shaking level on the ground surface. However, Intensity scales, like the Modified Mercalli Intensity Scale or the Japan Meteorological Agency’s Seismic Intensity Scale, do provide an indication of the extent and distribution of the damage caused from ground surface shaking caused by an earthquake.Intensity Witness Perceptions and Damage; I: Felt by very few people; barely noticeable.
