I understand much of this, including where the quake in 89 was centered. That said, the major damage was in the SF and Oakland areas, including many pancaked buildings and a pancaked section of freeway in which I have friends who had friends who died in there.
One friend was in a multi story brick building where the wall collapsed, and the floor sagged towards the missing wall, and he only stayed alive by hanging on to the carpet with his fingernails, as sliding out to his death was his worst nightmare. Of course he no longer lives in SF, or at least didn't last I had contact with him.
SF was hit as hard as it was for much the same reason Christchurch appears to have been, liquification of the soil, one because it's on an old riverbed, and the other because much of the city is built on fill. Tests have shown this to multiply the force of the quake, and it may well have been like a hard sideways jerk like the loma prieta quake, I remember to this day the sharp sideways motion even as far north as Santa Rosa.
