This was a small earthquake. Shaking like this is often felt indoors nearby and very rarely causes damage.

At this magnitude and depth, people at rest would likely notice it out to about 45 km (28 mi) from the epicentre. In Honaunau-Napoopoo, 15 km away, the estimate is intensity III (weak). Estimated from magnitude, depth and distance with the intensity equation USGS Did You Feel It? uses; felt reports, where there are any, are the measurement.

Likely felt in: Honaunau-Napoopoo 15 km, intensity III · Captain Cook 21 km, intensity II · Hawaiian Ocean View 30 km, intensity II · Hōlualoa 35 km, intensity II · Discovery Harbor 38 km, intensity II · Kailua-Kona 39 km, intensity II · Pāhala 39 km, intensity II. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 1,800 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.2 would have released about 32 times as much.

  2. Mineral, Virginia 2011 M 5.8 8,500× the energy of this one
  3. Magna, Utah 2020 M 5.7 6,000× the energy of this one
  4. This earthquake M 3.2 about 1,800 lb of TNT
  5. Around the size people start to feel M 3.0 this one released 1.9× 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 since 2016 was M 6.0 on 2026-05-23 — about 15,000 times the energy of this one.

Before 2016, the USGS record lists 19 earthquakes of M5 or more within 50 km; the five largest:

  1. 6.7 22 km W of Volcano, Hawaii · 41 km ENE of this epicentre
  2. 6.4 Kaoiki area, Hawaii · 46 km ENE of this epicentre
  3. 6.3 20 km SSW of Honaunau-Napoopoo, Hawaii · 12 km WSW of this epicentre
  4. 6.2 21 km N of Pahala, Hawaii · 40 km E of this epicentre
  5. 5.6 30 km WNW of Volcano, Hawaii · 38 km ENE 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.
