1. Mineral, Virginia 2011 M 5.8 140,000× the energy of this one
2. Magna, Utah 2020 M 5.7 99,000× the energy of this one
3. Around the size people start to feel M 3.0 8.8× the energy of this one
4. This earthquake M 2.4 about 110 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 5.3 on 2019-04-14 — about 29,000 times the energy of this one.
