The largest recorded earthquake … WebJul 5, 2024 · There are two commonly-used scales to rate earthquakes 1) the Richter Scale and 2) the Mercalli Scale. The force at which an earthquake shakes the ground is measured with the Richter Scale, which rates the earthquake's actual force on a scale from 0 to 9. A 0 level Richter rating cannot even be felt by a person, while a rating of 8 shakes hard ...
WebEarthquake size, as measured by the Richter Scale is a well known, but not well understood, concept. The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930's for measuring the size of earthquakes occurring in southern California using relatively high-frequency data from nearby seismograph stations. WebThe Richter scale measures the magnitude of earthquakes, and the Mercalli scale measures their intensity. It is based on the amplitude of seismic waves as recorded on standardized seismographs. ... Let's assume that you remember an earthquake a couple of years ago, which has a magnitude of 7.1. The Richter scale is used to rate the magnitude of ...
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 …
