Shimada Seamount is a

seafloor underneath Shimada is between 18 million and 21 million years old and lies at a depth of about 4,100 metres (13,500 ft); other than abyssal hills at a distance of up to 1 kilometre (0.62 mi) from Shimada, Shimada is isolated.[2] Volcanic rocks taken from Shimada are considered to be icelandites.[3]

Most seamounts form at

potassium-argon dating, and all the evidence indicates that volcanic activity at Shimada is of late Quaternary-Holocene age.[6]

Possibly alive Lithothamnium corals have been dredged at Shimada from a depth of 110 to 130 metres (360 to 430 ft).[7]

Shimada Seamount is named for the American fisheries scientist Bell M. Shimada (1922–1958).[8] It has been known under a variety of names throughout its history, including Shimada Bank, Shamada Seamount, Hurricane Bank and Allaire Bank.[9]
