WebThe Richter scale is used to rate the magnitude of an earthquake -- the amount of energy it released. This is calculated using information gathered by a seismograph. The Richter … 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 …

WebMay 6, 2024 · There are two commonly-used ways of rating earthquakes: 1) the Richter scale and 2) the Mercalli Scale. The Mercalli Scale was used earlier than the Richter Scale. It describes the damage left by an earthquake, not the actual force of the earthquake. WebThe Mercalli intensity scale uses personal reports and observations to measure earthquake intensity but PGA is measured by instruments, such as accelerographs. It can be correlated to macroseismic intensities on the Mercalli scale [3] but these correlations are associated with large uncertainty. [4] ( See also: seismic scale ).
