Most of those deaths were caused by subsequent …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 ...How Are Earthquakes Measured? Two different viewpoints underpin the most important measurements related to earthquakes: magnitude and intensity. To scientists, an earthquake is an event inside the earth. To the rest of us, it is an extraordinary movement of the ground. Magnitude measures the former, while intensity measures the latter. The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake. The USGS currently reports earthquake magnitudes using the Moment Magnitude scale, though many other magnitudes are calculated for research and comparison purposes.M L is the scale used for the majority of earthquakes reported (tens of thousands) by local and regional seismological observatories. For large earthquakes worldwide, the moment magnitude scale (MMS) is most common, although M s is also reported frequently. The severity of an earthquake is measured on a Richter scale. It is logarithmic scale that measures the magnitude of an earthquake. The scale ranges from 1 to 10, with each increase in number indicating a tenfold increase in ground motion. For example, an earthquake with a magnitude of 7 is ten times more powerful than an earthquake with a magnitude of 6.Richter magnitudes M L are computed on the assumption that the ratio of the maximum wave amplitudes at two given distances is the same for all earthquakes and is independent of azimuth. Richter first applied his magnitude scale to shallow-focus earthquakes recorded within 600 km of the epicentre in the southern California region. Later ...
