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 3 km (2 mi) from the epicentre. In Pāhala, 9 km away, the estimate is intensity II (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.

How big was it?

This earthquake released about 700 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.9 would have released about 32 times as much.

  1. Mineral, Virginia 2011 M 5.8 22,000× the energy of this one
  2. Magna, Utah 2020 M 5.7 15,000× the energy of this one
  3. Around the size people start to feel M 3.0 1.4× the energy of this one
  4. This earthquake M 2.9 about 700 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 970,000 times the energy of this one.

Before 2016, the USGS record lists 46 earthquakes of M5 or more within 50 km; the five largest:

  1. 7.7 17 km SSW of Leilani Estates, Hawaii · 43 km ENE of this epicentre
  2. 6.7 Island of Hawai`i, Hawaii · 42 km ENE of this epicentre
  3. 6.7 22 km W of Volcano, Hawaii · 22 km NNW of this epicentre
  4. 6.4 Kaoiki area, Hawaii · 22 km N of this epicentre
  5. 6.2 Kilauea South Flank, Hawaii · 42 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.
