DENDROLOGY

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 measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake. The USGS currently reports earthquake magnitudes using the Moment Magnitude scale, though many other magnitudes are calculated for research and comparison purposes.

Detailed explanation-3: -Magnitudes between 7.6 and 7.8 Earthquakes of this size might produce destructive tsunamis, especially near the epicenter. At greater distances, small sea level changes might be observed.

Detailed explanation-4: -Richter Scale is used to measure the magnitude of an earthquake. The more destructive earthquakes typically have magnitudes between about 5.5 and 8.9.
