#### Solution Preview

The magnitude (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 epicentre of the earthquakes. On the Richter Scale, magnitude is expressed in whole numbers and decimal fractions.

The equation for Richter Magnitude is:

ML = logA(mm) + (Distance correction factor)

Here log has logarithmic ...
