A magnitude 4.1 earthquake was recorded 48 km (30 mi) SW of Kekaha-Waimea, HI, at 8:25 am HST on 22 February 2026 (18:25 UTC). 4 people have reported feeling it to USGS. This was a light earthquake. It is usually felt clearly nearby and can rattle windows and dishes, but damage is uncommon.

How big was it?

This earthquake released about 24 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 5.1 would have released about 32 times as much.

  2. Mineral, Virginia 2011 M 5.8 310× the energy of this one
  3. Magna, Utah 2020 M 5.7 220× the energy of this one
  4. This earthquake M 4.1 about 24 tons of TNT
  5. Around the size people start to feel M 3.0 this one released 51× more

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 (31 mi) since our catalogue begins in 2016. The previous largest was M 4.0 on 2022-05-29.

Before 2016, the USGS record since 1900 lists no earthquake of M5 or more within 50 km.

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.
