Felt by 14 people across nearby locations.
On June 23, 2023 at 22:19 UTC, a magnitude 2.3 shallow crustal earthquake struck 4 km SE of Lewiston Orchards, Idaho, at a depth of 5.0 km and coordinates 46.3471°, -116.9364°. This earthquake was detected by 14 seismic stations with good location accuracy and was assigned a USGS significance rating of 85, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 42.5 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 23 m — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Idaho, a region characterized by the track of the Yellowstone hotspot and the Centennial Tectonic Belt, producing both volcanic and tectonic seismicity. View all earthquakes in Idaho.
