Earthquake near Hawthorne, NV

This was a small earthquake. Shaking like this is often felt indoors nearby and very rarely causes damage.

At this magnitude and depth, people at rest would likely notice it out to about 21 km (13 mi) from the epicentre. In Hawthorne, 40 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.

How big was it?

This earthquake released about 190 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.5 would have released about 32 times as much.

1. Mineral, Virginia 2011 M 5.8 78,000× the energy of this one
2. Magna, Utah 2020 M 5.7 55,000× the energy of this one
3. Around the size people start to feel M 3.0 4.9× the energy of this one
4. This earthquake M 2.5 about 190 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 870,000 times the energy of this one.

Before 2016, the USGS record lists 31 earthquakes of M5 or more within 50 km; the five largest:

1. 6.3 The 1934 Excelsior Mountains, Nevada Earthquake · 4 km NNW of this epicentre Jan 30, 1934
2. 6.1 Near Tonopah Junction, Nevada · 41 km SE of this epicentre Nov 21, 1910
3. 5.6 Excelsior Mountains, Nevada (Foreshock) · 8 km NW of this epicentre Jan 30, 1934
4. 5.6 37 km N of Dyer, Nevada · 35 km SE of this epicentre Aug 9, 1943
5. 5.5 Near Tonopah Junction, Nevada · 41 km SE of this epicentre Nov 19, 1910

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.
