The largest nearby quake this month, M2.7 at 60 km, was probably too small or too distant to notice in San Luis, AZ by a rough rule of thumb (an M3 is typically noticed within a few tens of km, an M5 up to a few hundred km; local ground and building type matter a lot).

None of the quakes listed has "Did You Feel It?" reports in the USGS feed, which usually means shaking at the surface was weak or the area has few reporters.
