Kolokol volcano is a group of young volcanoes on Urup Island, Kurile Islands. The principal volcanoes are Kolokol (the most prominent), Berg and Trezubetz.
Many eruptions of the Kolokol volcano group have been observed in historical time since the late 18th century. Berg volcano has been most active, but Trezubetz also erupted in 1924. Kolokol volcano (also known as Urup-Fuji because of its symmetrical profile) has not had any historic activity, but its morphology is young although its crater is not well preserved.

Background:

Berg and Trezubetz volcanoes, flanking Kolokol on the NW, have breached summit calderas partially filled by lava domes. Trezubetz, whose name means "trident," has an eroded crater rim with 3 large peaks when seen at sea from the north.
Several lava flows originate from Kolokol; one of these extends almost to the Sea of Okhotsk coast. A viscous lava flow armoring the SE flank is probably the most recent from Kolokol.
Borzov volcano, the oldest of the group, lies to the SW of Kolokol.
