Question 1137957: The Richter scale measures the energy released at the centre of an earthquake, (intensity)
of earthquakes and is measured according to the equation
log10 l/s, and if comparing 2 earthquakes, log l1/l2= log l1/s/l2/s
where is the intensity of the earthquake and S is the intensity of a standard earthquake
This is a logarithmic scale which runs from 1 to 9.5, where 7 is 10 times more intense than 6
and 100 times more intense than 5. In 1964 Alaska had an earthquake with a magnitude of
9.2 on the Richter scale How many times more intense was the Alaska earthquake than the
1994 California earthquake which had a magnitude of 6 4 and caused between $15 billion to
$30 billion in damage and killed 57 people?

can raise a log to the 10th power to remove it
so a 9.2 mag earthquake has relative energy of 10^9.2
the ratio of a 9.2 to a 6.4 is 10^9.2/10^6.4
This is 630.96 times more intense.
