A magnitude 3.3 earthquake was recorded 35 km (22 mi) W of Green River, WY, at 6:34 pm MST on 25 December 2024 (01:34 UTC). 3 people have reported feeling it to USGS. This was a small earthquake. Shaking like this is often felt indoors nearby and very rarely causes damage.
How big was it?
This earthquake released about 1.4 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.3 would have released about 32 times as much.

- Mineral, Virginia 2011 M 5.8 5,400× the energy of this one
- Magna, Utah 2020 M 5.7 3,800× the energy of this one
- This earthquake M 3.3 about 1.4 tons of TNT
- Around the size people start to feel M 3.0 this one released 2.9× more
Energy from the Gutenberg–Richter relation (log10E = 1.5M + 4.8), rounded to two figures; bar length is magnitude, which is already a logarithm of energy. Magnitudes of past earthquakes from the USGS catalogue.
For this area
No earthquake of M4 or more has been recorded within 50 km since our catalogue begins in 2016.
Before 2016, the USGS record lists one earthquake of M5 or more within 50 km:
- 5.2 8 km SE of Little America, Wyoming · 11 km SE of this epicentre
Since 2016: the QuakeIndex catalogue (US, M1.5+), built from the USGS FDSN event service. Before 2016: USGS ComCat, M5+ from 1900. Distances are between epicentres. This is the record, not a forecast.
