I understand your concern.  Lots of PSN members live in seismically active
areas so they provide the opportunity you recognized years ago to "densify"
the network of data recording in urban areas.  Other PSN members move to
states whose nicknames derive from sitting on kilometers of plutonic rock.
(Hint hint).  Hey, somebody has to provide data for triangulation!

The question is, should you put the strong motion sensor in the attic so
less of the house will fall on it?
