Admiralty Guyot

Admiralty Guyot is a large flat-topped submarine volcano in the Pacific Ocean. Its broad summit plateau is typical of a guyot, an underwater volcanic mountain shaped by erosion and later subsidence.

A guyot commonly formed as a volcanic island or seamount was eroded near sea level before sinking beneath the ocean. The surviving flat summit records that earlier geological history.

Admiralty Guyot is located in the Pacific Ocean. It is recorded as a named undersea geological feature rather than as a land-based mountain.

Its summit plateau and complex volcanic structure make it useful for studying submarine volcanism and seamount evolution. Deep-water geology also helps researchers understand how former volcanic islands sink over time.
