(a) just find M(1013.4)
(b) find E such that 2/3 log(E/10^(4.4)) = 7.2
The Richter scale measures earthquakes using the formula M =
2/3log(E/10^(4.4)) where M is the magnitude of the earthquake that releases E joules of energy.
(a) Find the magnitude of an earthquake that releases 1013.4
joules of energy.
(b) Find how much energy is released by an earthquake that has a magnitude of 7.2
