Kōkō Seamount

guyot near the southern end of the Emperor seamounts north of the bend in the Hawaiian-Emperor seamount chain.

Kōkō Seamount (光孝海山) is an underwater volcano (seamount) of the Hawaiian–Emperor seamount chain in the Pacific Ocean.[1] Kōkō is an extinct volcano.[2]

The undersea Emperor seamount chain includes Kōkō

The seamount is also known as the "Kōkō Guyot"' because it has a flat top.[3] This undersea geologic feature is also called a "guyot" or "tablemount".[4]

This seabed mountain is named after Emperor Kōkō of Japan.[5]

The last eruption from Kōkō seamount was 48 million years ago.[6] The north side of Kōkō Seamount was formed at least 52.6 million years ago; and the south side of Kōkō is dated at 50.4 million years ago.[7]
