Earthquake alerts for Pāhala, HI
Get a notification in this browser when USGS records an earthquake near Pāhala, HI. No account or email needed.
Alerts are on for .
Not a warning. An alert comes after USGS publishes a quake, usually minutes after the shaking. For early warning use ShakeAlert, through your phone's Wireless Emergency Alerts or the MyShake app.
This was a small earthquake. Shaking like this is often felt indoors nearby and very rarely causes damage.
At this magnitude and depth it was probably too small to be felt, even directly above it. In Pāhala, 18 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 490 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.8 would have released about 32 times as much.
- Mineral, Virginia 2011 M 5.8 31,000× the energy of this one
- Magna, Utah 2020 M 5.7 22,000× the energy of this one
- Around the size people start to feel M 3.0 1.9× the energy of this one
- This earthquake M 2.8 about 490 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 6.2 on 2021-10-10 — about 130,000 times the energy of this one.
Before 2016, the USGS record lists 42 earthquakes of M5 or more within 50 km; the five largest:
- 6.7 22 km W of Volcano, Hawaii · 41 km N of this epicentre
- 6.4 Kaoiki area, Hawaii · 41 km N of this epicentre
- 6.2 8 km SW of Volcano, Hawaii · 40 km NNE of this epicentre
- 6.2 21 km N of Pahala, Hawaii · 38 km N of this epicentre
- 6.2 13 km SSE of Fern Forest, Hawaii · 48 km NE 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.
