## One more question..

How would I go about converting intensity to magnitude? (earthquakes)

Richter of 6.1 = 1,258,925.412

But, I am unable to do the opposite! >.<

Intensities:

:39,877,000

:12,589,000

:251,200

If you'd use one for an example, that would be greatly appreciated.

The formula is

where is the intensity of a zero-level earthquake. Looking at this:

Richter of 6.1 = 1,258,925.412

So, for an intensity of 39,877,000,

.

You can do the other two.
