    Could this be considered a good thing?

    The energy being released in these many tiny earthquakes was always going to exist in this location. Much better to release it slowly via thousands of tiny earthquakes than all at once. Better to have 10k magnitude 3 quakes than one magnitude 7.

      How does the energy for the nuke itself factor into the equation though?

        A 150kt nuke has like 500,000x the energy release of a mag 3.0 earthquake, but as the article mentions that energy went into the original magnitude 6.3 event.
