This was a minor earthquake. Quakes this small are rarely felt and do not cause damage.

At this magnitude and depth, people at rest would likely notice it out to about 20 km (12 mi) from the epicentre. In Logan, 46 km away, the estimate is intensity II (weak). Estimated from magnitude, depth and distance with the intensity equation USGS Did You Feel It? uses; felt reports, where there are any, are the measurement.

Likely felt in: Tremonton 20 km, intensity II. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 110 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.4 would have released about 32 times as much.

Mineral, Virginia 2011 M 5.8 140,000× the energy of this one
Magna, Utah 2020 M 5.7 99,000× the energy of this one
Around the size people start to feel M 3.0 8.8× the energy of this one
This earthquake M 2.4 about 110 lb of TNT

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 8 earthquakes of M5 or more within 50 km; the five largest:

6.6 The 1934 Hansel Valley, Utah Earthquake · 37 km WSW of this epicentre Mar 12, 1934
6.1 17 km NE of Snowville, Utah · 34 km NNW of this epicentre Mar 28, 1975
5.9 35 km SSW of Howell, Utah · 38 km SW of this epicentre Mar 12, 1934
5.6 Hansel Valley, Utah · 27 km W of this epicentre Oct 6, 1909
5.2 27 km SW of Thatcher, Utah · 33 km SSW of this epicentre Apr 14, 1934

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.
