Things could be worse for San Francisco itself with a rupture that begins south of the city, than it was in 1906 when the rupture began very close to it.
We want to emphasize that a large earthquake such as 1906 is not just a San Francisco quake, but a Northern California earthquake. Earthquakes greater than magnitude 7 are going to cause intense shaking over a large area everyone needs to be prepared.
I'd be under the nearest table the second I felt the first shudder.
