(a)
To find: The comparison between the intensity of earthquake that was on
(a)

Answer to Problem 18PPS
The intensity of earthquake was on
Explanation of Solution
Given:
The given intensity of earthquakes are as:
In
And the famous San Francisco earthquake of
Calculation:
Since the Richter scale is used to measure earthquake intensity and it’s rounded to the nearest tenth.
So every increase of
The intensity of earthquake registered in
Here
The intensity of earthquake registered in
Suppose,
So
Solve the above expression is as:
So the intensity of earthquake was on
(b)
To find: The difference in intensities in between Richter himself classified and more recent research.
(b)

Answer to Problem 18PPS
The
Explanation of Solution
The more recent research indicates the earthquake was most likely a
Calculate the amplitude seismic value
Take the ratio of the two numbers then subtract
Therefore the
