Answer:

Magnitude 7.7 is 39811 times larger in amplitude compared to magnitude 3.1 .

Step-by-step explanation:

Magnitude scale doesn't use linear scale but uses base 10 logarithmic scale.

For example, if you go from magnitude 4 to 5, increase in amplitude is 10 times and not 1.

This is calculated by doing (10 ^ 5 / 10 ^ 4 ) = 10.

Let's move to the question.

( 10^7.7 / 10^3.1 ) = 38911

The answer is 38911.

How does an earthquake of magnitude 7.7 compare in intensity with an earthquake of magnitude of 3.1 on the Richter scale?

The Richter scale defines the magnitude of an earthquake to be R=log(IcIn) where Ic is the intensity of the earthquake and In is the intensity of a standard earthquake.

Magnitude 7.7 is 39811 times larger in amplitude compared to magnitude 3.1.

The Magnitude scale doesn't use a linear scale but uses a base 10 logarithmic scale.

This is calculated by doing (10 ^ 5 / 10 ^ 4 ) = 10.

Now the required answer is

( 10^7.7 / 10^3.1 ) = 38911
