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 ( 30 × 30 ) times the energy of a

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 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?
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
On November 1, 1755, Lisbon was destroyed by an earthquake, which killed 90,000 people and destroyed 85% of the city. It was one of the most destructive earthquakes in history The energy released measured 8x 10^17 joules. Calculate the magnitude of the 1755 Lisbon earthquake with the Richter scale.
