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

A large post-caldera cone (upper left) was constructed in the SE part of the Uratman caldera, the northernmost volcano on Simushir Island. The caldera is partially filled by Brouton Bay, shown here. Two cones and a lava dome are on the northern flank of the larger cone in this view from the NE caldera rim.

A narrow gap in the NNE rim of the Pleistocene Brouton caldera resulted in the formation of Brouton Bay. The caldera floor lies 250 m beneath the ocean surface and the rim rises 450 m above it.

A narrow gap in the NNE rim of 7.5-km-wide Pleistocene Brouton caldera on Uratman volcano in the Kuril Islands has led to the formation of the bay. The caldera floor lies 250 m beneath the ocean surface, and the rim rises 450 m above that. The central Uratman cone grew to a height of about 680 m during the Holocene.

The 7.5-km-wide Pleistocene Uratman caldera containing Brouton Bay and the cone along the SE rim are shown in this October 2018 Planet Labs satellite image monthly mosaic (N is at the top). A lava dome is within the bay and the caldera walls reach up to 450 m in height. Two scoria cones are on the N flank and a lava dome formed on the NW flank.
