Simushir, Volcanic island in Kuril archipelago, Russia
Simushir is a volcanic island in the Kuril chain featuring multiple stratovolcanoes, with the highest peak reaching about 1,540 meters (5,050 feet) above sea level. The island covers roughly 227 square kilometers (88 square miles) and is shaped by volcanic activity and steep, dramatic terrain.
The island passed between Russian and Japanese control through several treaties until 1945, when Soviet forces took command following World War II. This shift marked a turning point in the geopolitical history of the Kurils.
The Ainu people, who first lived here, named many places on the island using their own language, and these names remain visible on maps today. Walking through the island, you can see how this heritage shaped the way locals refer to the landscape.
Visiting requires special permits from Russian authorities and careful planning for transportation to this remote location in the North Pacific. The island's isolation and regulatory requirements mean advance arrangements are essential.
From 1987 to 1994, the Soviet Navy operated a submarine base in Brouton Bay that housed about 3,000 personnel at its peak. After the military left, few signs of this secret facility remain visible on the island.
