A magnitude 1.4 earthquake was recorded 30 km (19 mi) NNW of Anchor Point, AK, at 1:07 pm AKDT on 29 September 2026 (21:07 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 3.8 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 2.4 would have released about 32 times as much.

Mineral, Virginia 2011 M 5.8 4,000,000× the energy of this one
Magna, Utah 2020 M 5.7 2,800,000× the energy of this one
Around the size people start to feel M 3.0 250× the energy of this one
This earthquake M 1.4 about 3.8 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 5.4 on 2023-03-19 — about 1,000,000 times the energy of this one.
