WebThe Richter magnitude is the logarithm of the magnitude of an earthquake wave measured by seismographs. It is represented by Mʟ. Where ‘A’ represents the maximum magnitude of the earthquake in seismograph, and A (α) represents an empirical function whose value depends only upon the epicentral distance from the station ‘α’. The Richter scale , also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale". This was later revised and renamed the local magnitude scale, denoted as ML or ML . Because of various shortcomings of the original ML scale, most seismological authorities now u…

If an earthquake is powerful enough, it could cause windows, mirrors, or glass dishes inside of a house to crack and break from the violent ... WebThe Richter Scale is a base-ten logarithmic scale. In other words, an earthquake of magnitude 8 is not twice as great as an earthquake of magnitude 4. It is 108 − 4 = 104 = 10,000 times as great! In this lesson, we will investigate the nature of the Richter Scale and the base-ten function upon which it depends.
