Chapter 27, Problem 35TS
The Richter scale measure how much the ground shakes in an earthquake. Note that this is not equal to the energy released by an earthquake. However, there is a simple relationship between Richter magnitude and earthquake energy.
A 1- point increase on the Richter scale corresponds to
an energy increase of about 30 times. Thus, a 5.0-magnitude
earthquake releases about 30 times as much energy as
4.0-magnitude earthquake. The 5.0-magnitude earth-
quake releases about 900
3.0-magnitude quake.
(a) How much more energy does an 8.0-magnitudes earthquake release that a 7.0-magnititude earthquake?
(b) How much more energy does a 7.0-magnitudes earthquake release that a 5.0-magnititude earthquake?
(c) How much more energy does a 7.0-magnitudes earthquake release that a 4.0-magnititude earthquake?
(d) How much less energy does a 6.0-magnitudes earthquake release that a 7.0-magnititude earthquake?

The magnitude M of an earthquake is given.
a. Find the earthquake intensity I in terms of the zero-level earthquake intensity lo-
b. Find the energy released by the earthquake.
M = 7.3
The Richter scale describes how much energy an earthquake releases. With every increase of 1.0 on the scale, 32 times more energy is released. How many times more energy would be released by a quake measuring 2.0 more units on the Richter scale?
Energy release Consider these three events:
(1) On May 18, 1980, the volcanic eruption of Mount
St. Helens in Washington released approximately
1.7 X 1018 joules of energy.
(2) When a 1-megaton nuclear bomb detonates, it releases
about 4 X 1015 joules of energy.
(3) The 1989 San Francisco earthquake registered 7.1 on
the Richter scale.
(a) Make some comparisons (i.e., how many of one event
is equivalent to another) in terms of energy released.
(Hint: Refer to Exercise 70 in Chapter 5 Review Ex-
ercises.) Note: The atomic bombs dropped in World
War II were 1-kiloton bombs (1000 1-kiloton
bombs = 1 1-megaton bomb).
(b) What reading on the Richter scale would be equivalent
to the Mount St. Helens eruption? Has there ever been
a reading that high?
