Detroit Seamount is one of the few seamounts to break the naming scheme of the Emperor seamounts, which are named mostly after emperors or empresses of the Kofun period of Japanese history. It is instead named after the light cruiser USS Detroit.[5]
The Detroit Seamount is as big as the island of Hawaii.[1]
