Question

What is the difference in intensity of an earthquake of 6.2 and 4.5?

Answer 1

In Richter scale each number increases the intensity by

Explanation:

The `color(blue)"amplitude"` of earthquake is tenfolded as Richter scale increases by 1 (as the images above), but the `color(red)"energy"` will be `10^(1.5)=31.6` times larger if the scale goes 1 up.

So the intensity of scale `6.2` earthquake will be `10^(6.2-4.5)=50.1` times larger than that of scale `4.5`. Wikimedia.com.
