2026-05-17 08:04:18 UTC (45 min ago) · approx. 6:04 PM UTC+10 local
Maximum shaking intensity MMI 4.2 (moderate).
On May 17, 2026 at 08:04 UTC, a magnitude 5.7 shallow crustal earthquake struck 86 km ENE of Severo-Kuril’sk, Russia, at a depth of 56.0 km and coordinates 50.8432°, 157.3229°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 91 seismic stations with good location accuracy and was assigned a USGS significance rating of 500, placing it among routine seismic activity. The nearest populated place is Severo-Kuril'sk (population 2,485).
Physical scale: An earthquake of magnitude 5.7 releases seismic energy equivalent to roughly 5 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 5.2 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Russia, a region characterized by the Kuril-Kamchatka subduction zone on the northwestern Pacific Ring of Fire. The nearest mapped fault system is the Kuril-Kamchatka Trench. View all earthquakes in Russia.

The earthquake epicenter was located at 50.8432°, 157.3229°, which is 86 km ENE of Severo-Kuril’sk, Russia. The nearest populated place is Severo-Kuril'sk (population 2,485). View all earthquakes in Russia.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.7 earthquakes can continue for days to weeks and gradually diminish over time.
Has Russia had earthquakes this big before?
The largest recorded earthquake in Russia was the M9.0 Kamchatka earthquake of November 4, 1952. Today's magnitude 5.7 event is significantly smaller than that historical record.
What should I do after an earthquake?
If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
