From a scientific standpoint, the magnitude scale is based on seismic records while the Mercalli is based on observable data which can be subjective. Thus, the magnitude scale is considered scientifically more objective and therefore more accurate.

WebApr 25, 2024 · Light earthquakes are measured at between 4 and 4.9 on the magnitude scale, which is anywhere from a IV to a VI on the Mercalli intensity scale. These earthquakes result in noticeable shaking throughout homes and buildings, with objects rattling and sometimes falling off of shelves and walls. WebThe most common standard of measurement for an earthquake is the Richter scale, developed in 1935 by Charles F. Richter of the California Institute of Technology. The 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. dictum synonyms and antonyms
