Does any of the uptick in activity have anything to do with Soufriere?

What a year my friends... the earth is boiling tremendously

[Aslkahuna]

Not really, over a 12 month period we can expect an average of 17 MM7.0+ shocks with a range from 6 to 32. For the 12 month period ending April 14th there have been 18 MM7.0+ shocks globally.

On the VEI scale (or any other scientific scale) how does the eruption of Eyjafjallajökull compare to that of Soufiere a few months ago?
