No. This looks like a main shock (not a Northridge aftershock) followed by its own aftershocks. Pre-shocks don't act like this.

I always thought that you wouldn't know if it was a preshock until a few days passed and nothing bigger happened :) Each passing day the percentage of chance lessens. If I were to dig through my piles of articles I could come up with the numbers. Time to scan that mess onto cd.
