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 15 km (9 mi) from the epicentre. 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.

How big was it?

This earthquake released about 43 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.1 would have released about 32 times as much.

Mineral, Virginia 2011 M 5.8 350,000× the energy of this one
Magna, Utah 2020 M 5.7 250,000× the energy of this one
Around the size people start to feel M 3.0 22× the energy of this one
This earthquake M 2.1 about 43 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

The largest earthquake within 50 km since 2016 was M 6.5 on 2020-05-15 — about 4,000,000 times the energy of this one.

Before 2016, the USGS record lists 27 earthquakes of M5 or more within 50 km; the five largest:

6.8 The 1932 Cedar Mountain, Nevada Earthquake · 49 km N of this epicentre Dec 21, 1932
6.3 The 1934 Excelsior Mountains, Nevada Earthquake · 36 km WNW of this epicentre Jan 30, 1934
6.1 Near Tonopah Junction, Nevada · 18 km S of this epicentre Nov 21, 1910
5.6 Excelsior Mountains, Nevada (Foreshock) · 40 km WNW of this epicentre Jan 30, 1934
5.6 37 km N of Dyer, Nevada · 20 km SSW of this epicentre Aug 9, 1943

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.

Aftershocks so far

60 earthquakes have been recorded within 50 km since this one.

Counted from the QuakeIndex database, which ingests the USGS feed every 30 seconds · as of 19:34 UTC. QuakeIndex does not forecast aftershocks. When USGS issues an operational aftershock forecast it appears on the USGS event page.
