Felt by 9 people across nearby locations.
On June 17, 2020 at 21:08 UTC, a magnitude 4.5 shallow crustal earthquake struck 144 km WSW of Pistol River, Oregon, at a depth of 22.0 km and coordinates 41.7938°, -126.0193°.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — 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.
