- Mineral, Virginia 2011 M 5.8 68,000× the energy of this one
- Magna, Utah 2020 M 5.7 48,000× the energy of this one
- Around the size people start to feel M 3.0 4.3× the energy of this one
- This earthquake M 2.6 about 220 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 6.4 on 2020-01-07 — about 540,000 times the energy of this one.
