A magnitude 3.4 earthquake was recorded 29 km (18 mi) ENE of Hana, HI, at 3:12 am HST on 30 July 2016 (13:12 UTC). 1 person has reported feeling it to USGS. This was a small earthquake. Shaking like this is often felt indoors nearby and very rarely causes damage.

How big was it?

This earthquake released about 2.1 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.4 would have released about 32 times as much.

  1. Northridge, California 1994 M 6.7 80,000× the energy of this one
  2. Mineral, Virginia 2011 M 5.8 3,600× the energy of this one
  3. Magna, Utah 2020 M 5.7 2,500× the energy of this one
  4. This earthquake M 3.4 about 2.1 tons of TNT
  5. Around the size people start to feel M 3.0 this one released 4.4× 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

No earthquake of M4 or more has been recorded within 50 km since our catalogue begins in 2016.

Before 2016, the USGS record lists 6 earthquakes of M5 or more within 50 km; the five largest:

  1. 6.6 10 km ENE of Wailua, Hawaii · 36 km WNW of this epicentre
  2. 6.0 41 km NE of Hala‘ula, Hawaii · 42 km SSE of this epicentre
  3. 5.8 2 km WSW of Hana, Hawaii · 31 km WSW of this epicentre
  4. 5.6 Maui region, Hawaii · 36 km NW of this epicentre
  5. 5.0 North of Kohala, Hawaii · 42 km SSE 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.
