Just tossing this out here for some established guidelines to guage aftershocks...
Aftershock size and frequency with time
Aftershocks rates and magnitudes follow several well-established empirical laws.
The rate of aftershocks with time follows Omori's law. Omori's law, or more correctly the modified Omori's law, is an empirical relation for the
temporal decay of aftershock rates.
The other main law describing aftershocks is known as Båth's Law and this states that the difference in magnitude between a main shock and its
largest aftershock is approximately constant, independent of the main shock magnitude, typically 1.1–1.2 on the Moment magnitude scale.
Main article: Gutenberg–Richter law
Aftershock sequences also typically follow the Gutenberg–Richter law of size scaling, which refers to the relationship between the magnitude and
total number of earthquakes in a region in a given time period.
