It's tracked by some national agencies, for example NZ has a deformation model. This link has a summary & links to some lectures about the deformation model: https://www.linz.govt.nz/guidance/geodetic-system/coordinate-systems-used-new-zealand/geodetic-datums/new-zealand-geodetic-datum-2000-nzgd2000/new-zealand-geodetic-datum-2000-deformation-model https://www.linz.govt.nz/guidance/geodetic-system/coordinate... Metres of movement would definitely be significant for a lot of mapping use cases. This is why the time component of any coordinate measurement is important, both due to earthquakes as well as plain old plate motion.
