A magnitude 5.8 earthquake was recorded 262 km SSW of Severo-Kuril’sk, Russia at 16:48 UTC on 2026-10-06. 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 309 km (192 mi) from the epicentre. 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 7.6 kilotons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 6.8 would have released about 32 times as much.
- Ridgecrest, California 2019 M 7.1 89× the energy of this one
- Loma Prieta, California 1989 M 6.9 45× the energy of this one
- Northridge, California 1994 M 6.7 22× the energy of this one
- This earthquake M 5.8 about 7.6 kilotons of TNT
- Magna, Utah 2020 M 5.7 this one released 1.4× more
- Around the size people start to feel M 3.0 this one released 16,000× 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.
