An earthquake registers 6.1 on the richter scale. What is the rating on an earthquake twice as powerful?
I know: M=I/Io
Then what do you do?

Is the epicenter in the desert? In the mountains? In a city? Is it a strikeslip, normal, or thrust type of earthquake?

I'm sorry, I'm still confused.
Is it something like log(2) 6.1??

Add log 2 to 6.1

A seismograph 300 km from the epicenter of an earthquake recorded a maximum amplitude of 5.9 102 µm. Find this earthquake's magnitude on the Richter scale. (Round your answer to the nearest tenth.)
