Why Riverside gets earthquakes
Riverside sits between two of Southern California's most active fault zones: the San Jacinto fault zone, which passes just northeast through San Bernardino and Moreno Valley, and the Elsinore fault zone to the southwest. The San Jacinto produces more moderate quakes than any other fault in Southern California.
Historical events like the 1918 San Jacinto quake (M6.8) and the 1923 North San Jacinto event shook Riverside strongly. The city also lies close enough to the San Andreas that a major southern San Andreas rupture would cause severe shaking across the Inland Empire.
Riverside earthquake FAQ
▸Did Riverside just have an earthquake?
The live panel at the top of this page checks the USGS catalog for every earthquake within 150 km of Riverside and answers in one line. Keep in mind USGS data lags real shaking by roughly 2–3 minutes in California and up to ~8 minutes in other regions — if you felt something seconds ago, refresh shortly.
▸What faults cause earthquakes near Riverside?
Riverside is flanked by the San Jacinto fault zone to the northeast — Southern California's most active — and the Elsinore fault zone to the southwest. The San Andreas fault through the San Bernardino Mountains adds major-event risk to the whole Inland Empire.
▸What magnitude earthquake can you feel in Riverside, CA?
Close to the epicenter, people typically begin to feel earthquakes around magnitude 2.5–3.0. An M4+ is felt across a wide area and rattles objects; M5+ can damage buildings near the epicenter. Shallow quakes feel stronger than deep ones of the same magnitude, and soft soils amplify shaking.
▸What should I do if I feel an earthquake in Riverside?
Drop, Cover, and Hold On — get low, take cover under sturdy furniture, and hold on until shaking stops. Afterward, check for hazards like gas leaks, and expect possible aftershocks. If you're in a coastal area and the shaking is strong or lasts a long time, move inland or to high ground. Official guidance: ready.gov/earthquakes.
