Earthquake near Ridgecrest, CA

A magnitude 1.1 earthquake was recorded 46 km (29 mi) NNW of Ridgecrest, CA, at 12:02 pm PDT on 28 September 2026 (19:02 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 1.4 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 2.1 would have released about 32 times as much.

1. Mineral, Virginia 2011 M 5.8 10,000,000× the energy of this one
2. Magna, Utah 2020 M 5.7 7,400,000× the energy of this one
3. Around the size people start to feel M 3.0 660× the energy of this one
4. This earthquake M 1.1 about 1.4 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.
