Good morning

here's your answer

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.

Answer 2

Answer:

a numerical scale for expressing the magnitude of an earthquake on the basis of seismograph oscillations. The more destructive earthquakes typically have magnitudes between about 5.5 and 8.9; it is a logarithmic scale and a difference of one represents an approximate thirtyfold difference in magnitude.
