The example set in the webpage is to compare how much bigger would a 9.7 magnitude earthquake be in comparison to a 6.8 magnitude earthquake: The magnitude scale is logarithmic, so a magnitude 9.7 earthquake is 109.7 106.8 = 794.328 10 9.7 10 6.8 = 794.328 times bigger on the seismogram than a magnitude ... Jul 13, 2023 · Magnitude represents the energy released at the earthquake’s source, measured using logarithmic scales like Richter or Moment Magnitude scales. Intensity, on the other hand, quantifies the effects of an earthquake at specific locations, considering factors like damage to structures, ground shaking, and human perception. logES = 11.8 + 1.5M. giving the energy ES in ergs from the magnitude M.
