Колокол

Kolokol is a stratovolcano on Iturup Island in the Kuril chain, rising about 1328 meters above sea level and shaping the islands between Kamchatka and Japan. The mountain has steep slopes and a distinctive conical profile that clearly shows its volcanic origins.

The mountain formed through volcanic activity in the Pacific Ring of Fire and developed over long geological periods. Since recorded history began, the volcano has remained dormant, yet kept its importance as part of this active tectonic region.

The mountain carries two names: Kolokol in Russian and Tokachi Fuji in Japanese, reflecting the cultural connections of this remote island region. Visitors encounter places shaped by this dual heritage and different ways of seeing the landscape.

The best time to visit is during the warmer months when the weather is more stable and hiking trails are more accessible. Visitors should prepare for challenging terrain and bring warm, waterproof clothing and good hiking boots.

The mountain offers researchers rare opportunities to study volcanic structures and marine ecosystems in one location. This combination allows scientists to examine interactions between geological and biological systems in this remote region.
