The power of an earthquake is expressed in terms of a magnitude on a scale called the Richter scale. It is measured in Richter scale. It is measured with the help of instrument called seismograph. If the power of an earthquake is more than 7 on the Richter scale, it is dangerous. The Richter magnitude scale (often shortened to Richter scale) is the most common standard of measurement for earthquakes. It was invented in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. The Richter scale is used to rate the magnitude of an earthquake, that … Sep 29, 2023 · Enter the two magnitudes you want to compare – for our example, these are 5.8 and 7.1. We find out that a magnitude of 7.1 is 20 times bigger (on a seismogram, in terms of amplitudes) and ~89 times stronger (in terms of energy release) than a 5.8 magnitude. Remember that for each unit increase in magnitude: Evaluating Logarithmic Expressions Assignment. Richter defined the magnitude of an earthquake to be. M = log I/S , where I is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and S is the intensity of a "standard" earthquake, which is barely detectable. The magnitude of a standard earthquake is. The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs.It is a logarithmic scale that measures the energy released by an earthquake, with a magnitude of one being the lowest and a magnitude of 9 or higher being the highest. Earthquakes with a magnitude of 5 or higher are considered to be major events, while those with a magnitude of 7.0 or higher are known as great earthquakes.Inspired by the scale of magnitudes used by astronomers to determine the apparent brightness of stars from Earth, Richter set a minimum base value to which the maximum amplitudes of each earthquake would refer, thus giving a value of magnitude to each quake.
