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 30 km (19 mi) from the epicentre. 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: Leilani Estates in town, intensity III · Hawaiian Paradise Park 15 km, intensity III · Mountain View 23 km, intensity II. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 610 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 25,000× the energy of this one
  2. Magna, Utah 2020 M 5.7 18,000× the energy of this one
  3. Around the size people start to feel M 3.0 1.6× the energy of this one
  4. This earthquake M 2.9 about 610 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 1,100,000 times the energy of this one.

Before 2016, the USGS record lists 27 earthquakes of M5 or more within 50 km; the five largest:

  1. 7.7 17 km SSW of Leilani Estates, Hawaii · 18 km SSW of this epicentre
  2. 6.7 Island of Hawai`i, Hawaii · 17 km SW of this epicentre
  3. 6.2 Kilauea South Flank, Hawaii · 17 km SW of this epicentre
  4. 6.2 8 km SW of Volcano, Hawaii · 41 km W of this epicentre
  5. 6.2 13 km SSE of Fern Forest, Hawaii · 21 km SW 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.
