Was it felt in Walnut Creek?
The largest nearby quake this month, M3.3 at 77 km, was probably too small or too distant to notice in Walnut Creek 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); M3.1 on Oct 22, 2026 (9 reports, max intensity 2.1); M2.5 on Oct 20, 2026 (1 reports, max intensity 2); M2.5 on Oct 15, 2026 (3 reports, max intensity 2).
If you felt shaking, you can report it to USGS; reports refine the intensity map within minutes.
Tsunami warning status
4 earthquakes near Walnut Creek in the past year carried the USGS tsunami flag: M4.2 4 km SE of San Ramon, CA (Feb 2, 2026); M4.0 5 km S of San Juan Bautista, CA (Nov 27, 2025); M4.0 6 km W of Glen Ellen, CA (Dec 14, 2025); M4.0 8 km E of Gilroy, CA (Nov 26, 2025). The flag means the quake was large enough and in an oceanic region where tsunami warning centres issue messages; it does not mean a tsunami happened.
Official tsunami warnings come from the NOAA tsunami warning centres (tsunami.gov) and national agencies; follow local authorities if you are on a coast after strong shaking.
Earthquakes around the world today
Worldwide, USGS listed 146 earthquakes of M1+ in the last 24 hours; the largest was M6.5 Bonin Islands, Japan region.
USGS lists every magnitude in the United States but outside it coverage is complete only from about M4–4.5, so smaller local quakes reported by national agencies may be missing. Magnitudes and locations are revised for hours after an event.
