Was it felt in Martinez?
The largest nearby quake this month, M2.9 at 89 km, was probably too small or too distant to notice in Martinez 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 10 of these quakes: M2.7 on Nov 2, 2026 (3 reports, max intensity 3.1); M2.5 on Nov 2, 2026 (39 reports, max intensity 3.1); M2.5 on Nov 2, 2026 (2 reports, max intensity 3.1); M2.6 on Nov 2, 2026 (113 reports, max intensity 3.4).
If you felt shaking, you can report it to USGS; reports refine the intensity map within minutes.
Tsunami warning status
4 earthquakes near Martinez 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 170 earthquakes of M1+ in the last 24 hours; the largest was M6.1 Fiji 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.
