GEOLOGY

Detailed explanation-1: -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-2: -Although the Richter Scale has no upper limit, the largest known shocks have had magnitudes in the 8.8 to 8.9 range.

Detailed explanation-3: -The most common measure of earthquake strength is the Richter scale, which measures the “moment magnitude” and describes horizontal movement. It is a logarithmic scale. A magnitude 6 earthquake has ten times more energy intensity or movement than a magnitude 5 on the Richter scale.

Detailed explanation-4: -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-5: -1. Richter Scale is used to measure the scale of absolute ‘Magnitude’ of an earthquake based on the amount of seismic energy released. 2. Mercalli scale measures the ‘Intensity’ of an earthquake based on based on the amount of destruction caused.
