A magnitude 1.7 earthquake was recorded 6 km (3 mi) SSE of Pāhala, HI, at 3:39 am HST on 29 September 2026 (13:39 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 10 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 1,500,000× the energy of this one
- Magna, Utah 2020 M 5.7 1,100,000× the energy of this one
- Around the size people start to feel M 3.0 95× the energy of this one
- This earthquake M 1.7 about 10 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 6.2 on 2021-10-10 — about 6,200,000 times the energy of this one.
