Was it felt in Riverside?
The largest nearby quake this month, M3.6 at 100 km, was probably too small or too distant to notice in Riverside 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 11 of these quakes: M2.8 on Oct 15, 2026 (87 reports, max intensity 2.7); M2.7 on Oct 11, 2026 (58 reports, max intensity 2.9); M3.2 on Oct 9, 2026 (1091 reports, max intensity 3.4); M2.7 on Oct 8, 2026 (158 reports, max intensity 3.1).
If you felt shaking, you can report it to USGS; reports refine the intensity map within minutes.
Tsunami warning status
1 earthquake near Riverside in the past year carried the USGS tsunami flag: M4.3 20 km NNE of Indio, CA (Jan 21, 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 147 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.
