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 Volcano, 5 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 530 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 29,000× the energy of this one
- Magna, Utah 2020 M 5.7 20,000× the energy of this one
- Around the size people start to feel M 3.0 1.8× the energy of this one
- This earthquake M 2.8 about 530 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 1,300,000 times the energy of this one.
Before 2016, the USGS record lists 43 earthquakes of M5 or more within 50 km; the five largest:
- 7.7 17 km SSW of Leilani Estates, Hawaii · 26 km ESE of this epicentre
- 6.7 Island of Hawai`i, Hawaii · 24 km ESE of this epicentre
