Tyatya

Tyatya is a stratovolcano on Kunashir Island standing at 1,819 meters with a symmetrical cone shape. The steep flanks display multiple lava flows that have formed over many eruption cycles.

The volcano experienced a major eruption in 1973 that released substantial volcanic ash across Kunashir Island. This event left lasting marks on the island's landscape and regional records.

The mountain carries a name from the Ainu language, 'Chacha-Nupuri,' meaning 'Old Man Mountain' in the indigenous terminology. This name reflects the long history of native people who have known this landscape for generations.

The volcano remains under Russian administration and requires special permits for visits. Visitors should contact the Russian-Japanese visa-free exchange program or local authorities to explore access options.

The 1973 eruption left a distinctive feature behind: expanses of dead trees forming a skeletal forest across the slopes. These bare areas remain visible in satellite imagery, revealing the power of that volcanic event.
