- Mineral, Virginia 2011 M 5.8 78,000× the energy of this one
- Magna, Utah 2020 M 5.7 55,000× the energy of this one
- Around the size people start to feel M 3.0 4.9× the energy of this one
- This earthquake M 2.5 about 190 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
No earthquake of M4 or more has been recorded within 50 km since our catalogue begins in 2016.
