Was it felt in Eureka?
The largest nearby quake this month, M3.4 at 81 km, was probably too small or too distant to notice in Eureka 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: M3.4 on Oct 23, 2026 (1 reports, max intensity 3.1); M3.3 on Oct 22, 2026 (13 reports, max intensity 3.4); M2.6 on Oct 17, 2026 (1 reports, max intensity 3.1); M2.9 on Oct 15, 2026 (3 reports, max intensity 2.2).
If you felt shaking, you can report it to USGS; reports refine the intensity map within minutes.
Tsunami warning status
1 earthquake near Eureka in the past year carried the USGS tsunami flag: M4.7 85 km W of Petrolia, CA (Aug 29, 2026). 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 145 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.
