This was a moderate earthquake. Shaking at this size can damage poorly built structures close to the epicentre.

At this magnitude and depth, people at rest would likely notice it out to about 195 km (121 mi) from the epicentre. In Pāhala, 7 km away, the estimate is intensity V (moderate). 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: Pāhala 7 km, intensity V · Discovery Harbor 18 km, intensity IV · Hawaiian Ocean View 30 km, intensity IV · Volcano 43 km, intensity IV. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 510 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 6.0 would have released about 32 times as much.

  2. Mineral, Virginia 2011 M 5.8 15× the energy of this one

  4. This earthquake M 5.0 about 510 tons of TNT
  5. Around the size people start to feel M 3.0 this one released 1,100× 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 6.2 on 2021-10-10 — about 61 times the energy of this one.

Before 2016, the USGS record lists 41 earthquakes of M5 or more within 50 km; the five largest:

  1. 6.7 22 km W of Volcano, Hawaii · 32 km N of this epicentre
  2. 6.4 Kaoiki area, Hawaii · 34 km NNE of this epicentre
  3. 6.3 20 km SSW of Honaunau-Napoopoo, Hawaii · 48 km WNW of this epicentre
  4. 6.2 8 km SW of Volcano, Hawaii · 35 km NE of this epicentre
  5. 6.2 21 km N of Pahala, Hawaii · 29 km N 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.
