Portland, OR – A light earthquake struck off the Oregon coast Wednesday afternoon, according to new data released by the U.S. Geological Survey (USGS). The magnitude-4.1 quake was recorded at 15:12 UTC (7:12 a.m. PST), centered well offshore in the Pacific Ocean.
According to USGS, the earthquake occurred at a depth of about 10 kilometers. While the offshore location placed the shaking away from populated areas, residents in several coastal communities may have felt mild tremors. As of Wednesday morning, only a small number of “Did You Feel It?” responses had been submitted.
USGS aftershock forecasts show a 10% chance of a magnitude-3.0 or greater aftershock within the next week. Probabilities for stronger activity—including magnitude-5.0 or higher—remain under 1%, suggesting limited risk to the region at this time.
Oregon’s coastline sits near the Cascadia Subduction Zone, one of North America’s most active seismic regions. While Wednesday’s event is considered routine for the offshore seismic landscape, emergency officials often remind residents that earthquakes of any size highlight the importance of preparedness, especially for those living near the Pacific.
No damage or tsunami warnings were issued as a result of the quake, and normal operations continued for coastal cities including Newport, Florence, and Coos Bay. USGS will continue monitoring the area for additional seismic activity.
Residents who felt shaking are encouraged to submit a report to USGS to assist scientists in mapping intensity across the region.
