Felt by 18 people across nearby locations.
On February 26, 2024 at 19:00 UTC, a magnitude 2.8 shallow crustal earthquake struck 8 km NNW of Smiths Ferry, Idaho, at a depth of 12.5 km and coordinates 44.3698°, -116.1261°. This earthquake was detected by 26 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 127, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.8 releases seismic energy equivalent to roughly 239 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 52 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.
