If the infrastructure is up to the task and it would actually be doable (say release fault pressure with a magnitude 5 earthquake every 3 years via some sort of method) it might not be such a bad idea. Way easier to build for a planned magnitude 5.x quake every few years vs a 7 or 8 at unknown time intervals.

Heck it could even be fun. Make it a holiday, tell people the time its going to happen and let them ride it out. Personally, I'd be at a bar. :)
