The Global Volcanism Program is not aware of any Holocene eruptions from Uratman. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Uratman page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

A composite panorama from the NE rim of Brouton caldera on Urataman volcano shows the crescent-shaped Brouton Bay, which fills the caldera floor through a narrow gap in the NNE caldera rim (right). A small settlement on the NE shore of the bay lies at the foot of Urataman, a central cone constructed in the SE part of the caldera. The 7.5-km-wide caldera was formed during the Pleistocene.

A large post-caldera central cone (upper left) was constructed in the SE part of the caldera of Urataman volcano, the northernmost of six Quaternary volcanoes on Simushir Island. Urataman consists of a 7.5-km-wide Pleistocene caldera that forms the NE tip of the island. The walls of the caldera rise 450 m above a 250-m-deep caldera floor, partially filled by the half-moon-shaped Brouton Bay. Two cinder cones and a lava dome are seen on the northern flank of the cental cone along Brouton Bay in this view from the NE caldera rim.

A narrow gap in the NNE rim of 7.5-km-wide Pleistocene Brouton caldera on Urataman volcano in the Kuril Islands allows access of the sea into Brouton Bay. The caldera floor lies 250 m beneath the sea surface, and the rim rises 450 m above it. A central cone, andesitic Urataman volcano, has grown to a height of 678 m during the Holocene in the SE part of the caldera.
