On June 15, 2022 at 11:56 UTC, a magnitude 5.6 shallow crustal earthquake struck near off the coast of Oregon, at a depth of 10.0 km and coordinates 44.5381°, -130.1124°.0 The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 158 seismic stations with good location accuracy and was assigned a USGS significance rating of 487, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.6 releases seismic energy equivalent to roughly 4 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 4.4 km — 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.

Common Questions

How strong was the magnitude 5.6 earthquake near off the coast of Oregon?

The magnitude 5.6 earthquake that struck near off the coast of Oregon on June 15, 2022 at 11:56 UTC had a depth of 10.0 km. For context, this was a moderate earthquake that could be widely felt.

Where did the earthquake occur?

The earthquake epicenter was located at 44.5381°, -130.1124°, which is near off the coast of Oregon. View all earthquakes in Oregon.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.6 earthquakes can continue for days to weeks 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 5.6 event is significantly smaller than that historical record.
