M4.3 Earthquake 19 km ESE of Joseph, Oregon — November 10, 2026
2026-11-10 07:42:52 UTC (1 hour ago) · approx. 11:42 PM UTC-8 local
Felt by 52 people across nearby locations. Maximum shaking intensity MMI 4.2 (moderate).
On November 10, 2026 at 07:42 UTC, a magnitude 4.3 shallow crustal earthquake struck 19 km ESE of Joseph, Oregon, at a depth of 2.5 km and coordinates 45.2677°, -117.0203°. The earthquake was reported felt by 52 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.2 (moderate). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 19 seismic stations with good location accuracy and was assigned a USGS significance rating of 304, placing it among routine seismic activity. The nearest populated place is Joseph (population 1,252).
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 41 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 550 m — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Oregon, a region characterized by the southern Cascadia Subduction Zone, with additional seismicity from crustal faults in the Willamette Valley. The nearest mapped fault system is the Cascadia Subduction Zone. View all earthquakes in Oregon.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.3 earthquakes can continue for several days and gradually diminish over time.
Has Oregon had earthquakes this big before?
The largest recorded earthquake in Oregon was the M7.3 offshore Brookings earthquake of November 23, 1873. Today's magnitude 4.3 event is significantly smaller than that historical record.
