Where can I get official earthquake information for Oregon?
For official information, warnings and safety advice, follow Pacific Northwest Seismic Network (https://pnsn.org/) and your local civil protection authority. This site compiles agency reports and is not a warning service.
How are earthquakes assigned to Oregon on this page?
An earthquake is listed in Oregon when the nearest town to its epicentre, within 200 km, is in the state. Earthquakes farther offshore are not included. Counts of magnitude 2.5 and above are comparable between states; smaller earthquakes depend on how dense the local seismic network is.
Can earthquakes be predicted?
No. Scientists can estimate how likely strong shaking is in a region over years or decades, but no method predicts the time, place and size of a specific earthquake. Aftershocks are expected after large earthquakes and become less frequent over time.
