89 km N of Cruz Bay, U.S. Virgin Islands

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 6 km (4 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 2 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.4 would have released about 32 times as much.

2. Mineral, Virginia 2011 M 5.8 3,700× the energy of this one
3. Magna, Utah 2020 M 5.7 2,600× the energy of this one
4. This earthquake M 3.4 about 2 tons of TNT
5. Around the size people start to feel M 3.0 this one released 4.3× 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

The largest earthquake within 50 km since 2016 was M 5.7 on 2023-12-09 — about 2,600 times the energy of this one.

Before 2016, the USGS record lists 16 earthquakes of M5 or more within 50 km; the five largest:

1. 6.2 131 km NNE of Cruz Bay, U.S. Virgin Islands · 46 km NNE of this epicentre Sep 6, 1919
2. 6.1 91 km N of Charlotte Amalie, U.S. Virgin Islands · 10 km WNW of this epicentre Oct 11, 2008
3. 6.0 112 km N of Charlotte Amalie, U.S. Virgin Islands · 31 km NW of this epicentre Oct 17, 2001
4. 5.9 68 km N of Cruz Bay, U.S. Virgin Islands · 22 km S of this epicentre Jun 25, 1930
