This was a light earthquake. It is usually felt clearly nearby and can rattle windows and dishes, but damage is uncommon.

At this magnitude and depth, people at rest would likely notice it out to about 116 km (72 mi) from the epicentre. In Honaunau-Napoopoo, 28 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 28 km, intensity III · Pāhala 32 km, intensity III · Captain Cook 34 km, intensity III · Volcano 39 km, intensity III · Hōlualoa 40 km, intensity III · Kailua-Kona 46 km, intensity III · Discovery Harbor 48 km, intensity III · Hawaiian Ocean View 48 km, intensity III. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 35 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 5.2 would have released about 32 times as much.

  4. This earthquake M 4.2 about 35 tons of TNT
  5. Around the size people start to feel M 3.0 this one released 72× 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 5.5 on 2019-03-13 — about 89 times the energy of this one.

Before 2016, the USGS record lists 32 earthquakes of M5 or more within 50 km; the five largest:

  1. 6.7 22 km W of Volcano, Hawaii · 17 km ESE of this epicentre
  2. 6.4 Kaoiki area, Hawaii · 22 km ESE of this epicentre
  3. 6.3 20 km SSW of Honaunau-Napoopoo, Hawaii · 40 km WSW of this epicentre
  4. 6.2 8 km SW of Volcano, Hawaii · 33 km ESE of this epicentre
  5. 6.2 21 km N of Pahala, Hawaii · 18 km ESE 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.
