From Wikipedia
Tyatya is an active volcano located in the northeastern part of Kunashir Island, Kuril Islands, Russia. It is the highest peak on the island with an elevation of 1,819 metres (5,968 ft). Tyatya is one of the finest examples anywhere in the world of a somma volcano, a stratovolcano whose summit has collapsed to form a caldera which has then been mostly refilled by a new, younger volcanic cone which rises above the caldera rim.
