If the Caldera ever blows in our life time a dictator is what we would have and it really would be the least of our concern.
Good point.
So far they have not been able to determine the strength however I don't think it was that large, judging by the webicorder capture.
What is interesting though is that this indeed might be a fore-runner quake. Looking over these graphs, I find the motion of this quake interesting. It was also very shallow.

here is the info still no determination on the strength.
Magnitude ? (uncertain or not yet determined)
