At this magnitude and depth, people at rest would likely notice it out to about 54 km (34 mi) from the epicentre. In Somerset, 21 km away, the estimate is intensity III (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.

- Mineral, Virginia 2011 M 5.8 50,000× the energy of this one
- Magna, Utah 2020 M 5.7 35,000× the energy of this one
- Around the size people start to feel M 3.0 3.1× the energy of this one
- This earthquake M 2.7 about 310 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.
