A magnitude 0.6 earthquake was recorded 22 km (14 mi) NW of Big Spring, TX, at 7:34 pm CDT on 1 October 2026 (00:34 UTC). This was a minor earthquake. Quakes this small are rarely felt and do not cause damage.
How big was it?
This earthquake released about 0.24 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 1.6 would have released about 32 times as much.
- Mineral, Virginia 2011 M 5.8 63,000,000× the energy of this one
- Magna, Utah 2020 M 5.7 45,000,000× the energy of this one
- Around the size people start to feel M 3.0 4,000× the energy of this one
- This earthquake M 0.6 about 0.24 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 5.1 on 2024-09-17 — about 5,600,000 times the energy of this one.
Before 2016, the USGS record since 1900 lists no earthquake of M5 or more within 50 km.
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.
