I was once more reassured than anything after fairly strong quakes, subscribing to the theory that they "released pressure" and that a larger quake was unlikely to follow. The big quake up here completely trashed that theory. There were a couple of pretty big shakers in the few weeks immediately prior to the Big One, and one that was about a 5, I think, just two or three days before.
Not trying to be a scaremonger or anything, just suggesting caution for a while.
There was a 7.2 on March 9th followed by almost hourly M4 ~ M6 quakes until around 7am on the 11th.
