  2. The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included to compensate for the variation in the distance between the various seismographs and the epicenter of the earthquake.

  3. Oct 19, 2024 · Richter scale, widely used quantitative measure of an earthquake’s magnitude (size), devised in 1935 by American seismologists Charles F. Richter and Beno Gutenberg. Magnitude is determined using the logarithm of the amplitude (height) of the largest seismic wave calibrated to a scale by a seismograph.

  4. Apr 11, 2005 · The Richter scale was developed in 1935 by American seismologist Charles Richter (1891-1989) as a way of quantifying the magnitude, or strength, of earthquakes.

  5. Jul 19, 2023 · The Richter scale is a logarithmic scale that measures the magnitude of an earthquake, originally developed by Charles F. Richter in 1935. It provides an objective measure of the energy an earthquake releases by quantifying the seismic waves produced.

  6. The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included for the variation in the distance between the various seismographs and the epicenter of the earthquakes.

  7. Apr 11, 2012 · The Richter scale, developed by the American geologist Charles Richter in the 1930s, is a "logarithmic" scale, which means that each one-point increase on the scale represents a tenfold...

  8. The Richter scale calculates an earthquake's magnitude (size) from the amplitude of the earthquake's largest seismic wave recorded by a seismograph.
