Question 6

An earthquake with a magnitude of about 2.0 or less is called a microearthquake. It is not usually felt. The intensity of an earthquake with a magnitude of 2 is how many times greater than the intensity of an a standard earthquake?

Revolt · Accepted Answer

100 times greater

Question 7

How many more times intense is an earthquake that measures 8 on the Richter scale than an earthquake that measures 5? Explain your answer.

Revolt · Accepted Answer

A magnitude 8 earthquake is 1,000 times more intense than a magnitude 5 earthquake. This is because each unit on the Richter scale represents a 10-fold increase in intensity. Since the difference between 8 and 5 is 3 units, the intensity difference is 10 to the power of 3 (10^3), which equals 1,000.

Question 8

In 2010, Haiti was hit by a devastating earthquake, which registered at 7.0 on the Richter scale. The largest recorded earthquake since 1900 occurred in 1960 in Valdivia, Chile, and registered at 9.5 on the Richter scale. About how many times greater was the intensity of the Chilean earthquake?

Revolt · Accepted Answer

316

Question 9

What is the intensity of an earthquake with a magnitude of 3?

Revolt · Accepted Answer

1,000 times a standard earthquake

Question 10

Which did you include in your answer?

Revolt · Accepted Answer

A magnitude 8 earthquake is 1,000 times more intense than a magnitude 5 earthquake.; A magnitude 8 earthquake is 108 times more intense than a standard earthquake, while a magnitude 5 earthquake is 105 times more intense than a standard earthquake, and 108 ÷ 105 = 103.; Each unit increase on the Richter scale corresponds to an intensity increase by a factor of 10. So from 5 to 8 on the Richter scale, the intensity increases by 103 = 1,000
