I remember a Seismologist that said that moving rocks in a region with fault lines are a good sign. At least better than not moving rocks that are constantly building pressure. Of course "we don't know" is probably the most accurate prediction.
The small energy released by small movements doesn't add up to a large earthquake. For example, magnitude 8 earthquake is a billion times more energy than a magnitude 3 earthquake. This was the sobering perspective of a geophysicist when I asked if small earthquakes are a good thing in California to help relieve potential energy.
