Answer:
1000 times
Step-by-step explanation:
The Richter scale is a logarithmic scale, so we can say an earthquake of magnitude 8 on the Richter scale shows an intensity of 10^8.
In the same way, an earthquake of magnitude 5 on Richter scale will have an intensity of 10^5.
To evaluate the difference, we divide one by the other.
10^8 / 10^5 = 10^3 = 1,000
An earthquake of intensity of 8 is 1,000 times more powerful than one of intensity 5.
Answer:
on edge
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.
