# Amazing Earthquakes

## Introduction

Earthquakes can make the ground shake a lot. Earthquakes can be caused by the earth’s crust shifting. Most of the earthquakes happen along the earth’s ring of fire. The Ring of Fire is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. The movement of the earth can put a lot of stress on large blocks of rolling fault.

## Devastation

When an earthquake occurs the devastation that it brings is often massive. An earthquake can destroy homes, cottages, hospitals, land and people. The devastation can happen in Japan, Turkey, Indonesia and the west coast of North America. The devastation can be measured by the Richter scale. The numbers on a Richter scale go from 4-8. A 4 is a minor attack an 8 is a major damage.

## Interesting Facts

## This is the Richtor Scale

Richter Scale

4Minor Earthquake

5Moderate Earthquake

6Strong Earthquake

7Major Earthquake

8Great Earthquake

## This is how you calculate how big an earthquake is

10**8.7)/(10**5.8) = (5.01*10**9)/(6.31*10**6) = .794*10**3 = 794 OR = 10**(8.7-5.8) = 10**2.9 = 794.328
