[Westbrook]

Remember, the Richter scale is exponential.

A mag 7 quake, like the one that hit Haiti, is TEN TIMES greater than a mag 6 quake, like the one that just hit Venezuela.

Nevertheless, we need to wait and see what happened on the ground.

Remember, the Richter scale is exponential.

Yes it is. It is Logarithmic.

That means each number 10 times the previous.

6 is 10 times as strong as 5, 7 is 10 times as strong as 6 8 is 10 times as strong as 7.
