Joseph, OR – A magnitude 4.3 earthquake struck northeastern Oregon early Tuesday, November 10, near the Idaho border, sending seismic waves through a mountainous region of the Pacific Northwest and prompting reports of shaking.
According to the U.S. Geological Survey USGS , the earthquake occurred at 11:42 p.m. Pacific time Monday, November 9, corresponding to 07:42 UTC Tuesday. The epicenter was approximately 12 miles east southeast of Joseph, Oregon, at a depth of just 1.6 miles 2.5 kilometers .
The earthquake struck in Wallowa County, a rural area of northeastern Oregon near the Idaho state line. The surrounding region includes communities such as Enterprise and Joseph, with Lewiston, Idaho, farther north and Boise to the south.
Because the earthquake occurred at a relatively shallow depth, shaking may have been noticeable near the epicenter. However, the strength of shaking experienced at individual locations can vary depending on distance, terrain and local ground conditions.
The USGS earthquake information page displayed a maximum reported shaking intensity of IV on the Modified Mercalli Intensity Scale, indicating light shaking. At this intensity, shaking can be felt indoors, and dishes, windows or doors may rattle.
The agency's preliminary PAGER assessment was green, suggesting a low likelihood of significant earthquake related fatalities or economic losses.
The USGS also displayed an aftershock forecast estimating a 45% chance of at least one magnitude 3 or greater aftershock within the following week. The estimated probability of a magnitude 4 or greater aftershock was 11%.
No confirmed injuries or major structural damage were identified in the information provided.
Residents who experienced shaking can submit reports through the USGS "Did You Feel It?" program, helping scientists document the earthquake's effects across Oregon and Idaho.
Officials encourage residents to remain aware of possible aftershocks and follow standard earthquake safety guidance.
