Earthquakes are described in terms of what nearby residents felt and the damage that was done to nearby structures. Richter magnitude scale. Developed in 1935 by Charles Richter, this scale uses a seismometer to measure the magnitude of the largest jolt of energy released by an earthquake. Moment magnitude scale.The magnitude is based on the seismic moment of the earthquake, which is equal to the rigidity of the Earth multiplied by the average amount of slip on the fault and the size of the area that slipped. The scale was developed in the 1970s to succeed the 1930s-era Richter magnitude scale (ML).Aug 29, 2017 · While the Richter scale is logarithmic, the Mercalli scale is linear. The measuring tool used in a Richter scale is a seismograph while observation is used on the Mercalli scale. The Richter scale is absolute which means that wherever an earthquake is registered, it will have the same measurement on the Richter scale. Oct 3, 2023 · Developed in 1934 by Charles F. Richter, the Richter scale was the first method that gained widespread acceptance for measuring earthquakes. The scale relies on the amplitude of the largest seismic wave recorded and accounts for the distance between the earthquake's epicenter and the recording seismometer. The Richter Scale (more accurately referred to now as the “local magnitude” scale or ML), like all other magnitude scales to follow, is logarithmic, meaning each unit up on the scale equals a 10-fold increase in amplitude–e.g. a 7.0 earthquake is 10 times stronger than a 6.0 earthquake, and 100 times stronger than a 5.0 earthquake.Magnitude is a measure of the total energy released during an earthquake. It is determined from a seismogram, which plots the ground motion produced by seismic waves. As devised by C.F. Richter in 1935, the magnitude scale allows us to compare earthquakes in relative terms.The Mercalli and Richter scales are both used when measuring the impacts of seismic activity.
