Was it felt in Windsor, CA?
The largest nearby quake this month, M3.7 at 77 km, was probably too small or too distant to notice in Windsor, CA 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).
USGS "Did You Feel It?" received reports for 9 of these quakes: M2.5 on Oct 24, 2026 (1 reports, max intensity 2); M2.5 on Oct 20, 2026 (1 reports, max intensity 2); M2.8 on Oct 15, 2026 (1 reports, max intensity 2); M3.2 on Oct 10, 2026 (13 reports, max intensity 2.8).
