How about Planetized Back Yard (*) Medium LBI? If you, the measurement
enthusiast, have decent gps hardware + see yourself as 1 point in the LBI + have
good timestamps for your measurement + a decent protocol to combine them I would
say "Radio astronomy for fun & profit!". Mostly fun in this case! Combine your
local datapoints + gps derived datestamps (and estimate of uncertainty) with
those of fellow enthusiasts around the planet. Certainly looks like fun, and it
might even be useful. ;)
(*) Scale in a "back yard" concepts is a relative thing after all...

That should be within reason for a semi-nut. All it takes is a good GPS
setup. The ballpark motion of the San Andreas fault is an inch per year.
Around here (Silicon Valley), it's reasonably common to see USGS monitoring
stations along the side of the road. There is a big sturdy tripod with a
foot diameter antanna and a dome on top with a fence around it. There is one
on the right as you are going south on101 a bit south of San Jose.
