A magnitude 6.1 earthquake struck the Kuril Islands at 18:35 UTC on June 13, 2025, according to the Japan Meteorological Agency (JMA). The quake was shallow, occurring at a depth of just 10 km (6.2 miles), which often increases the intensity of ground shaking.
Both the US Geological Survey (USGS) and European-Mediterranean Seismological Centre (EMSC) confirmed the same magnitude and depth.
Epicenter and Impact
The earthquake’s epicenter was located approximately:
- 443 km (275 miles) east of Kuril’sk, Russia (population: ~1,600)
- 694 km (431 miles) east-northeast of Nemuro, Japan (population: ~31,200)
Despite its strength and shallow depth, the remote location of the quake meant that no significant population centers were directly affected.
No Tsunami, Minimal Risk
The Pacific Tsunami Warning Center reported no tsunami threat from this event.
The USGS issued a Green alert, indicating a low likelihood of casualties or economic damage. Most structures in the region are built to withstand moderate seismic activity, though some vulnerable buildings—such as adobe block and unreinforced brick with mud construction—do exist.
