On May 6, 2026 at 00:51 UTC, a magnitude 2.7 earthquake struck 10 km E of Bonanza, Oregon. At a depth of just -1.7 km, this was a very shallow event, close enough to the surface that modest magnitudes can produce significant local shaking. The event was offshore — common for earthquakes along subduction zones and transform plate boundaries. The epicenter is at 42.209°, -121.282°. The solution has been reviewed by a USGS seismologist and is considered finalized. See the M2.7 event page for the full report, ShakeMap, and citizen-reported intensity data.
