The famous log scale. |
|
|
|
If you live in California
you should be familiar with a famous log scale. |
|
|
It is called the Richter
Scale, it measures an earthquake's power. |
|
|
|
So an earthquake with a
Richter reading of |
4 |
|
|
has
a certain power. If another earthquake with a Richter reading of |
5 |
|
|
occurs, how much more
powerful is it. |
|
|
|
Since Richter readings
are in log form then a 5 is 10 times more powerful than a 4 |
|
|
So the difference between
a 3 and a 7 magnitude is substantial. |
|
|
A 7 is 10,000 more
powerful than a 3. |
