This was a small earthquake. Shaking like this is often felt indoors nearby and very rarely causes damage.

At this magnitude and depth, people at rest would likely notice it out to about 53 km (33 mi) from the epicentre. 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 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.5 would have released about 32 times as much.

Mineral, Virginia 2011 M 5.8 2,800× the energy of this one
Magna, Utah 2020 M 5.7 2,000× the energy of this one
This earthquake M 3.5 about 2.7 tons of TNT
Around the size people start to feel M 3.0 this one released 5.6× 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

The largest earthquake within 50 km since 2016 was M 7.6 on 2020-10-19 — about 1,400,000 times the energy of this one.

Before 2016, the USGS record lists 13 earthquakes of M5 or more within 50 km; the five largest:

6.6 85 km SE of Sand Point, Alaska · 39 km NNE of this epicentre Oct 9, 1985
6.1 79 km SE of Sand Point, Alaska · 34 km NNE of this epicentre Nov 14, 1985
6.0 71 km SSE of Sand Point, Alaska · 35 km N of this epicentre Jun 27, 1918
5.9 113 km SE of Sand Point, Alaska · 47 km ENE of this epicentre Jun 7, 1917
5.9 99 km SE of Sand Point, Alaska · 32 km NE of this epicentre Oct 20, 1929

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.

Aftershocks so far

No further earthquakes have been recorded within 50 km since this one.

Counted from the QuakeIndex database, which ingests the USGS feed every 30 seconds · as of 15:02 UTC. QuakeIndex does not forecast aftershocks. When USGS issues an operational aftershock forecast it appears on the USGS event page.
