A light magnitude 4.6 earthquake struck 86 km NE of Otrada, Russia on Wednesday, August 26, 2026 at 07:32:17 AM UTC. This intermediate focal depth (163.8 km depth) released energy equivalent to approximately 120 tons of TNT. Here is the verified US telemetry, live epicenter map, and ground shaking assessment.

A magnitude 4.6 event is classified as a light earthquake. Noticeable shaking of indoor objects and rattling doors/windows. Generally causes none to slight non-structural damage in older buildings.
Felt only by a few persons at rest, especially on upper floors.
Help seismologists and community members map real-world ground shaking near Russia.
Your immediate response verifies shaking boundaries and helps ground-truth instrumental models.
Earthquake strength is measured on a logarithmic scale. Compare this event with the full seismic scale:
Because seismic scales are logarithmic, each whole integer increase represents:
Russia's seismicity is fundamentally governed by its tectonic setting: Pacific Plate subducting beneath the Okhotsk/North American Plate along the Kuril-Kamchatka Trench at ~80 mm/year, plus the active Baikal continental rift zone. Major regional fault structures include Kuril-Kamchatka Trench, Baikal Rift Zone, Greater Caucasus Thrust Faults.
Originating at a depth of 163.8 km (Upper Mantle / Wadati-Benioff Zone (70–300 km)), this rupture occurred originated within the descending oceanic plate inside the upper mantle. shaking radiates over a wider geographic area with attenuated high frequencies.
Seismologists note that minor aftershocks remain common in the 24 to 48 hours following tremors of magnitude 4.6. According to statistical seismic models, there is roughly a 5% probability of a subsequent event of equal or greater strength occurring in the same fault zone. Residents in Russia are advised to check living spaces for unsecured items.
