Expert Solution
Step 1: Introduction

Magnitude of an earthquake is defined as the measure of the destruction of an earthquake. 

It is the measure of the size or amplitude of the seismic waves generated due to an Earthquake. 

A ritcher scale is used to measure the the magnitude. It contains numbers 1-10. 

Increasing 1 fold on the ritcher scale increases 10 fold in magnitude. 

If one earthquake has a magnitude of 3 and another earthquake has a magnitude of 5 the magnitude increases 100 fold.
