Felt by 12 people across nearby locations.
On September 28, 2024 at 03:04 UTC, a magnitude 5.1 shallow crustal earthquake struck 169 km WSW of Pistol River, Oregon, at a depth of 14.7 km and coordinates 41.8723°, -126.3717°. This earthquake was detected by 68 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 403, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
