I'm in Silicon Valley. The San Andreas fault is a few miles from here. A
map of the bay area will show a dozen major faults. A neighborhood map may
have several smaller lines.
The USGS has good GPS receivers sprinkled around the area. You can see
antenna domes on a post alongside the highway.
(Time sink warning.)
The fault moves about as fast as your fingernails grow, an inch per year.
That's one side relative to the other. I don't know how fast the pair is
These are my opinions. I hate spam.
