On February 6, 2024 at 16:04 UTC, a magnitude 3.5 shallow crustal earthquake struck 21 km NNW of Clayton, Idaho, at a depth of 13.9 km and coordinates 44.4441°, -114.4983°. The earthquake was reported felt by 3 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.2 (light).

Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 m — a useful intuition for the size of the slip patch on the fault.

Common Questions

How strong was the magnitude 3.5 earthquake near Clayton, Idaho?

The magnitude 3.5 earthquake that struck 21 km NNW of Clayton, Idaho on February 6, 2024 at 16:04 UTC had a depth of 13.9 km. It was felt by 3 people with maximum shaking intensity of MMI 3.2 (light). For context, this was a minor earthquake typically detected only by instruments.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.5 earthquakes can continue for several days and gradually diminish over time.

Understanding This Data

Magnitude 3.5 earthquakes are typically only recorded by instruments.
