Earthquake alerts for Volcano, HI

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 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 247 km (153 mi) from the epicentre. In Volcano, 7 km away, the estimate is intensity VI (strong). 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: Volcano 7 km, intensity VI · Mountain View 25 km, intensity V · Pāhala 30 km, intensity IV · Hawaiian Paradise Park 39 km, intensity IV · Leilani Estates 39 km, intensity IV · Hilo 42 km, intensity IV. Estimated for each town centre; each link is that town's own record.
USGS catalogues this as volcanic eruption, not an earthquake.
How big was it?
This earthquake released about 1.9 kilotons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 6.4 would have released about 32 times as much.
- Northridge, California 1994 M 6.7 89× the energy of this one
- Mineral, Virginia 2011 M 5.8 4× the energy of this one
- Magna, Utah 2020 M 5.7 2.8× the energy of this one
- This earthquake M 5.4 about 1.9 kilotons of TNT
- Around the size people start to feel M 3.0 this one released 4,000× 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 6.9 on 2018-05-04 — about 180 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 · 30 km ESE of this epicentre
- 6.7 Island of Hawai`i, Hawaii · 28 km ESE of this epicentre
- 6.7 22 km W of Volcano, Hawaii · 18 km W of this epicentre
- 6.4 Kaoiki area, Hawaii · 13 km WNW of this epicentre
- 6.2 Kilauea South Flank, Hawaii · 28 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.
