42km S of Qualeys Camp, NV

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 8 km (5 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 10 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 2.7 would have released about 32 times as much.

1. Mineral, Virginia 2011 M 5.8 1,500,000× the energy of this one
2. Magna, Utah 2020 M 5.7 1,100,000× the energy of this one
3. Around the size people start to feel M 3.0 95× the energy of this one
4. This earthquake M 1.7 about 10 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 5.2 on 2020-04-11 — about 220,000 times the energy of this one.

Before 2016, the USGS record lists 54 earthquakes of M5 or more within 50 km; the five largest:

1. 6.4 The 1986 Chalfant Valley, California Earthquake · 45 km SSE of this epicentre Jul 21, 1986
2. 6.3 The 1934 Excelsior Mountains, Nevada Earthquake · 42 km NNE of this epicentre Jan 30, 1934
3. 6.1 Near Tonopah Junction, Nevada · 48 km E of this epicentre Nov 21, 1910
4. 6.1 11 km WNW of Aspen Springs, California · 45 km SSW of this epicentre May 25, 1980
5. 6.1 8 km W of Aspen Springs, California · 48 km SSW of this epicentre May 25, 1980

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.
