GEOLOGY

Detailed explanation-1: -The moment magnitude scale is based on the total moment release of the earthquake. Moment is a product of the distance a fault moved and the force required to move it. It is derived from modeling recordings of the earthquake at multiple stations.

Detailed explanation-2: -Moment Magnitude Scale MMS measures the movement of rock along the fault. It accurately measures larger earthquakes, which can last for minutes, affect a much larger area, and cause more damage. The Moment Magnitude can measure the local Richter magnitude (ML), body wave magnitude (Mb), surface wave magnitude (Ms).

Detailed explanation-3: -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-4: -The Richter scale is a logarithmic scale that measures the largest jolt of energy released by an earthquake. The moment magnitude scale is a logarithmic scale that measures the total amount of energy released by an earthquake.

Detailed explanation-5: -Moment Magnitude is more effective for large earthquakes Moment Magnitude uses more variables to calculate the energy released using seismic moment. Seismic moment combines the seismic energy with offset on the fault and rigidity of rock. Noodles can be used to teach relative magnitude.
