Axial Seamount's growth has intersected the growth of many of the smaller seamounts around it. The largest of these is Brown Bear Seamount, to which it is connected by a narrow ridge running roughly perpendicular to its western caldera wall. However, little evidence of interactions between the two seamounts has been found. On the other hand, Axial Seamount's southern rift zone bisects Vance Seamount by as much as , creating a zone of intense fissuring at the northern edge of the smaller volcano. Interactions with Cobb Seamount to the north are more complex, forming an unusual bent spreading center. In addition there are four smaller structures directly east, north, and south of Axial.
