Funny as the Whittier quake extracted more damage on my house than Northridge. Although Northridge was a wild ride.
Quakes actually direct their energy in many cases like rayguns. It's not surprising at all that you would have had more damage from Whittier....I presume you are further south in the LA area.
I was living in La Crescenta for the Whittier event, and that one scared the hell out of me. But other than the mirror separating from my chest of drawers, I did all right.
