I suspect that they are not sensitive enough for seismic work, although
I could be wrong.  It's likely that eventually they will be, mind you...
One notion that's being pursued at the research stage is adding a
scanning-tunneling-microscope probe to the bottom of the sensing mass,
so that movements of a fraction of an atomic diameter can be detected;
this would be several orders of magnitude more sensitive than the best
accelerometers (of any kind) built to date.
