Kōkō Seamount

From Simple English Wikipedia, the free encyclopedia
The undersea Emperor seamount chain includes Kōkō

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 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]
