A magnitude 2.4 earthquake was recorded 6 km (4 mi) WSW of Volcano, HI, at 11:26 pm HST on 30 September 2026 (09:26 UTC). This was a minor earthquake. Quakes this small are rarely felt and do not cause damage.
Earthquakes near other towns within 30 km: Fern Forest, Eden Roc, Fern Acres, Mountain View, Hawaiian Acres.
How big was it?
This earthquake released about 140 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.4 would have released about 32 times as much.
- Mineral, Virginia 2011 M 5.8 110,000× the energy of this one
- Magna, Utah 2020 M 5.7 78,000× the energy of this one
- Around the size people start to feel M 3.0 6.9× the energy of this one
- This earthquake M 2.4 about 140 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 4,900,000 times the energy of this one.
