A magnitude 1.7 earthquake was recorded 26 km (16 mi) SW of Anchor Point, AK, at 5:47 am AKDT on 1 October 2026 (13:47 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 11 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 2.7 would have released about 32 times as much.

  1. Mineral, Virginia 2011 M 5.8 1,400,000× the energy of this one
  2. Magna, Utah 2020 M 5.7 1,000,000× the energy of this one
  3. Around the size people start to feel M 3.0 89× the energy of this one
  4. This earthquake M 1.7 about 11 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 5.6 on 2017-03-02 — about 710,000 times the energy of this one.

Before 2016, the USGS record lists 11 earthquakes of M5 or more within 50 km; the five largest:

  1. 6.4 25 km NW of Nanwalek, Alaska · 14 km SW of this epicentre
  2. 6.2 16 km WNW of Happy Valley, Alaska · 45 km N of this epicentre
  3. 6.0 53 km W of Anchor Point, Alaska · 43 km WNW of this epicentre
  4. 5.9 Southern Alaska · 46 km WSW of this epicentre
  5. 5.8 23 km WNW of Happy Valley, Alaska · 46 km N of this epicentre

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.
