Magnitude 5.6 Earthquake Depth 394 km Strikes Northwest of Kuril Islands on 12th January 2026
The Kuril Islands consist of the Greater Kuril Chain and, at the southwest end, the parallel Lesser Kuril Chain. The group termed the ‘South Kurils’ consists of those of the Lesser Kuril Chain together with Kunashir and Iturup in the Greater Kuril Chain. The Vries Strait between Iturup and Urup forms the Miyabe Line dividing the North and South Kurils. The Kuril Islands cover an area of around 10,503.2 square kilometres (4,055.3 sq mi), with a population of roughly 20,000.
The islands have been under Russian administration since their 1945 invasion by the Soviet Union near the end of World War II. Japan claims the four southernmost islands, including two of the three largest (Iturup and Kunashir), as part of its territory, as well as Shikotan and the unpopulated Habomai islets, which has led to the ongoing Kuril Islands dispute. The disputed islands are known in Japan as the country’s “Northern Territories”.
