On the island is the highest point of this group of islands with a height of 749 meters. It is separated from its northern neighboring island of Tschirpoi by the narrow Snou Strait .

Brat Tschirpojew is located on the southern edge of two overlapping calderas with a diameter of 8 to 9 kilometers. The neighboring island of Tschipoi emerged in the center of the calderas. Brat Tschirpojew consists of parts of a basalt volcano that existed before the calderas were formed. There are no reports of eruptions in historical times; the island's geomorphology suggests recent Strombolian eruptions .
