    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.

      Geologic systems are more complex than this. Analyzing something like this as though it were a single system is wrought with the dangers of miscalculation.

      You could locally release stresses on an incremental, short term basis this way in a local system, while at the same time increasing stresses on nearby systems which could fail even more spectacularly, especially if the increasing stresses are being moved from a less dangerous system to a more dangerous system.

      I'm not suggesting the above is true in this case, but that you need to cast a pretty wide net with increasingly unknown (and perhaps unknowable) variables as you start to inject real changes into a local system and try to predict what those changes will actually do.
