This was a minor earthquake. Quakes this small are rarely felt and do not cause damage.

At this magnitude and depth it was probably too small to be felt, even directly above it. Estimated from magnitude, depth and distance with the intensity equation USGS Did You Feel It? uses; felt reports, where there are any, are the measurement.

How big was it?

This earthquake released about 2.7 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 2.3 would have released about 32 times as much.

Mineral, Virginia 2011 M 5.8 5,600,000× the energy of this one
Magna, Utah 2020 M 5.7 4,000,000× the energy of this one
Around the size people start to feel M 3.0 350× the energy of this one
This earthquake M 1.3 about 2.7 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 4.9 on 2021-05-09 — about 250,000 times the energy of this one.

Before 2016, the USGS record lists 5 earthquakes of M5 or more within 50 km:

6.1 109 km E of McCarthy, Alaska · 29 km SSE of this epicentre Jul 7, 1920
5.5 87 km ENE of McCarthy, Alaska · 17 km NW of this epicentre Nov 23, 1987
5.4 140 km SSE of Alcan Border, Alaska · 44 km E of this epicentre Jun 10, 1972
5.3 136 km E of McCarthy, Alaska · 39 km E of this epicentre Apr 29, 2004
5.2 130 km SSE of Alcan Border, Alaska · 49 km ENE of this epicentre Dec 22, 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.
