A magnitude 2.5 earthquake was recorded 47 km (29 mi) ESE of Cedar City, UT, at 11:46 am MST on 9 February 2019 (18:46 UTC). This was a minor earthquake. Quakes this small are rarely felt and do not cause damage.

How big was it?

This earthquake released about 150 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.5 would have released about 32 times as much.

Mineral, Virginia 2011 M 5.8 100,000× the energy of this one
Magna, Utah 2020 M 5.7 72,000× the energy of this one
Around the size people start to feel M 3.0 6.5× the energy of this one
This earthquake M 2.5 about 150 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.

Before 2016, the USGS record since 1900 lists no earthquake of M5 or more within 50 km.

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.
