GEOLOGY

Detailed explanation-1: -The Richter magnitude scale (often shortened to Richter scale) is the most common standard of measurement for earthquakes. It was invented in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes.

Detailed explanation-2: -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.

Detailed explanation-3: -The Richter Scale Richter in 1934. It used a formula based on the amplitude of the largest wave recorded on a specific type of seismometer and the distance between the earthquake and the seismometer.

Detailed explanation-4: -Richter Scale. While the Mercalli scale describes the intensity of an earthquake based on its observed effects, the Richter scale describes the earthquake’s magnitude by measuring the seismic waves that cause the earthquake. The two scales have different applications and measurement techniques.

Detailed explanation-5: -An earthquake has only one magnitude determined from measurements on seismographs. The first widely-used measurement was the Richter scale. It is now considered outdated and the Moment Magnitude Scale (Mw) is deemed more accurate-a strong earthquake would be typically described as 8.5 Mw magnitude.
