unusual but not unprecedented

There are a few creeping faults around the world, and sometimes they have "slow" earthquakes taking hours rather than creeping at a steady pace or have normal earthquakes lasting just seconds.

There is indeed some redistribution of stress at the time of the slow earthquakes, either catching up with the forces from below or just from an instability of the creeping fault.

Attempts to link times of accelerated creep to enhanced probability of earthquakes have been unsuccessful - these episodes apparently do not make the surrounding faults much more dangerous.
