Detailed explanation-1: -Richter scale (ML), quantitative measure of an earthquake’s magnitude (size), devised in 1935 by American seismologists Charles F. Richter and Beno Gutenberg. The earthquake’s magnitude is determined using the logarithm of the amplitude (height) of the largest seismic wave calibrated to a scale by a seismograph.

Detailed explanation-2: -The Richter scale is a scale that seismologists use to measure the amount of ground shaking and energy that is released from earthquakes.

Detailed explanation-3: -A seismograph is the primary earthquake measuring instrument. The seismograph produces a digital graphic recording of the ground motion caused by the seismic waves. The digital recording is called a seismogram. A network of worldwide seismographs detects and measures the strength and duration of the earthquake’s waves.

Detailed explanation-4: -While the Richter scale is not obsolete, the universal measurement today is the moment magnitude scale. The Richter scale was developed by seismologist Charles Richter (1900-1985) in the 1930s to bring consistent, objective criteria to evaluating the size of earthquakes.
