    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.

      It's logarithmic so you'd need more like 30,000 magnitude 3 earthquakes to equal the energy of a magnitude 7. I don't think it's clear this is better. You can also make the argument that this may trigger the large earthquake that might not have happened for a long time.

        So even if this does release pressure with no negative side effects anywhere it isn’t actually useful for preventing “the big one”.
