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 335 km (208 mi) from the epicentre. In Charleston, 21 km away, the estimate is intensity IV (light). 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: Charleston 21 km, intensity IV · East Prairie 26 km, intensity III · New Madrid 49 km, intensity III. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 3.7 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.6 would have released about 32 times as much.

- Mineral, Virginia 2011 M 5.8 2,100× the energy of this one
- Magna, Utah 2020 M 5.7 1,500× the energy of this one
- This earthquake M 3.6 about 3.7 tons of TNT
- Around the size people start to feel M 3.0 this one released 7.7× 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
No earthquake of M4 or more has been recorded within 50 km since our catalogue begins in 2016.
Before 2016, the USGS record since 1900 lists no earthquake of M5 or more within 50 km.
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.
