Well, is not my goal to map the whole extension of a fault, but just the
visible portions like where there is shear terrain indications or waviness in
known faults or unstable terrain due to faults, not the actual extension of San
Andreas, I agree that there is several Geological Maps were this data is
depicted, not in OSM.

Geological faults should not go into the OSM data base, only visible features
should go into OSM. This may include visible features that are caused by
geological faults, including, in particular, features that mark such faults on
the surface.
Specialised maps of geological faults exist and can be consulted by experts.
Such maps could be meshed with OSM data to produce maps combining surface
features and underground features.

I mean, can we actually map a fault that's several / 0's / 00's klm under
the ground?
As David said though, really just a guess as I've also never been involved
in that sort of thing.
Thanks
