What does amplitude mean in earthquakes?
GeologyThe amplitude is the size of the wiggles on an earthquake recording. How does amplitude affect earthquakes? The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included in the magnitude formula to compensate for the variation in the distance between the various seismographs and
