A magnitude 1.7 earthquake was recorded 11 km (7 mi) E of Pāhala, HI, at 11:20 am HST on 2 October 2026 (21:20 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.

Mineral, Virginia 2011 M 5.8 1,400,000× the energy of this one
Magna, Utah 2020 M 5.7 970,000× the energy of this one
Around the size people start to feel M 3.0 86× the energy of this one
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 6.9 on 2018-05-04 — about 61,000,000 times the energy of this one.

Before 2016, the USGS record lists 48 earthquakes of M5 or more within 50 km; the five largest:

7.7 17 km SSW of Leilani Estates, Hawaii · 42 km ENE of this epicentre Nov 29, 1975
6.7 Island of Hawai`i, Hawaii · 41 km ENE of this epicentre Sep 21, 1908
6.7 22 km W of Volcano, Hawaii · 27 km NNW of this epicentre Nov 16, 1983
6.4 Kaoiki area, Hawaii · 26 km N of this epicentre Mar 28, 1915
6.2 Kilauea South Flank, Hawaii · 41 km ENE of this epicentre May 4, 1905

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.
