How are Earthquakes Measured? Magnitude
WebThe magnitude is based on the seismic moment of the earthquake, which is equal to the rigidity of the Earth multiplied by the average amount of slip on the fault and the size of … WebApr 6, 2024 · The scale of Richter is also known as the Richter Magnitude Scale. It is said to be a measure of the strength of earthquakes which was developed by Charles F. Richter and presented in his landmark 1935 paper. where he named it the "magnitude scale". Later this was revised and renamed the local magnitude scale that was denoted as ML or ML .
