Northridge, California 1994 M 6.7 200,000× the energy of this one
Mineral, Virginia 2011 M 5.8 9,100× the energy of this one
Magna, Utah 2020 M 5.7 6,500× the energy of this one
This earthquake M 3.2 about 1,700 lb of TNT
Around the size people start to feel M 3.0 this one released 1.7× 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 lists 3 earthquakes of M5 or more within 50 km:

6.0 The 2014 South Napa, California Earthquake · 30 km SE of this epicentre Aug 24, 2014
5.3 3 km E of Bloomfield, California · 30 km WSW of this epicentre Oct 2, 1969
5.3 Northern California · 31 km WSW of this epicentre Oct 2, 1969

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.
