Well, who knows what the minor quakes mean. They could be good at relieving tension along the faults.
It was only a few years ago that I was made aware that Yellowstone could destroy the USA, if Obozo does not do it first.
If these are 3.0 or less and a volcano unleashes a 8.0 you would need about 100,000 small quakes to relieve that tension or even more maybe 1 million. In short small quakes in no way can prevent the big one, only delay it a little bit.
