How does the mercalli scale rate earthquakes
WebThe Mercalli Scale Another way to measure the strength of an earthquake is to use the observations of the people who experienced the earthquake, and the amount of damage that occurred, to estimate its intensity. WebMagnitude calculations are based on a logarithmic scale, so a ten-fold drop in amplitude decreases the magnitude by 1.If an amplitude of 20 millimetres as measured on a seismic signal corresponds to a magnitude 2 earthquake, then:10 times less (2 millimetres) corresponds to a magnitude of 1;100 times less (0.2 millimetres) corresponds to …
