A magnitude 1.3 earthquake was recorded 29 km (18 mi) N of Ridgecrest, CA, at 5:59 pm PDT on 29 September 2026 (00:59 UTC). This was a minor earthquake. Quakes this small are rarely felt and do not cause damage.
Earthquakes near other towns within 30 km: China Lake Acres, Inyokern, Searles Valley.
How big was it?
This earthquake released about 2.4 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 2.3 would have released about 32 times as much.
- Mineral, Virginia 2011 M 5.8 6,200,000× the energy of this one
- Magna, Utah 2020 M 5.7 4,400,000× the energy of this one
- Around the size people start to feel M 3.0 390× the energy of this one
- This earthquake M 1.3 about 2.4 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 7.1 on 2019-07-06 — about 560,000,000 times the energy of this one.
