A magnitude 0.7 earthquake was recorded 65 km ENE of Pedro Bay, Alaska at 12:47 UTC on 2026-10-05. This was a minor earthquake. Quakes this small are rarely felt and do not cause damage.

How big was it?

This earthquake released about 0.34 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 1.7 would have released about 32 times as much.

Mineral, Virginia 2011 M 5.8 45,000,000× the energy of this one
Magna, Utah 2020 M 5.7 32,000,000× the energy of this one
Around the size people start to feel M 3.0 2,800× the energy of this one
This earthquake M 0.7 about 0.34 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 7.1 on 2016-01-24 — about 4,000,000,000 times the energy of this one.

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.
