Live seismic activity in Oregon — updated every 60 seconds from USGS data. Oregon's coast sits above the Cascadia Subduction Zone, and crustal faults add moderate activity inland.

Oregon's coast sits above the Cascadia Subduction Zone, which can produce earthquakes of about M9 and tsunamis that would reach the coast within roughly 15 to 30 minutes. Shallow crustal faults beneath Portland and in the south of the state add further hazard. Major faults include the Cascadia Subduction Zone, Portland Hills Fault, Gales Creek Fault, and faults of the Klamath Graben. Notable quakes include the 1993 Klamath Falls earthquakes (M5.9 and M6.0), the 1993 Scotts Mills earthquake (M5.6) and the 1700 Cascadia earthquake (about M9). The seismic risk is high. Tectonically, Oregon lies on the North American Plate, where the Juan de Fuca Plate subducts beneath it. This page provides real‑time USGS data and historical context for Oregon.

The region is defined by Cascadia Subduction Zone, Portland Hills Fault, Gales Creek Fault, Klamath Graben faults, and the risk level is classified as High. With a population of 4.2 million, understanding local seismic hazards is crucial.
Oregon lies on Juan de Fuca Plate subducting beneath North American Plate. The movement of these plates builds up stress, which is released as earthquakes. In subduction zones, one plate dives beneath another, generating some of the largest quakes on Earth. In some regions, strike‑slip faults produce frequent moderate earthquakes.

The strongest recorded earthquake in Oregon was the 1993 Klamath Falls earthquake (M5.9). 1993 Klamath Falls (M5.9 and M6.0)
Oregon experiences approximately 200-500 earthquakes per year, with 20-50 felt (M3.0+) and 2-5 potentially damaging events (M5.0+) annually, according to USGS historical data.
The most recent major earthquake in Oregon was the 1993 Klamath Falls earthquake (M5.9). 1993 Klamath Falls (M5.9 and M6.0)
Yes. Oregon is crossed by Cascadia Subduction Zone, Portland Hills Fault, Gales Creek Fault, Klamath Graben faults, making it prone to seismic activity. The seismic risk level is classified as High.
Drop, cover, and hold on. Stay away from windows, and if outdoors, move to an open area. After the shaking stops, check for injuries and be ready for aftershocks. Prepare an emergency kit with water, food, first aid, and a flashlight.
