Zavaritski Caldera, Caldera volcano in Simushir Island, Russia.
Zavaritski is a stratovolcano on Simushir Island in the Kuril chain, rising to approximately 624 meters above sea level. The structure contains three nested calderas, with Lake Biryuzovoe filling the youngest of these formations.
The volcano's last recorded eruption occurred between November and December 1957, marking a significant event in the geological history of the Kuril Islands. This recent eruptive activity demonstrates the system remains geologically active.
The name honors Alexander Nikolayevich Zavaritski, a scientist who made significant contributions to Soviet scientific research. Visitors can observe how this volcanic site carries the memory of important scientific achievements.
Visiting requires special permits and transportation arrangements due to the remote location in the Kuril Islands. Accessibility depends heavily on weather conditions and logistical considerations.
The volcanic structure features three distinct nested calderas, each representing a separate period of volcanic activity in the region. These multiple formations offer insight into the complex eruption history spanning different geological time periods.
