description Ogasawara Guyot Overview
Ogasawara Guyot is a flat-topped submarine mountain in the western Pacific near the Ogasawara Islands, also known as the Bonin Islands. A guyot is a seamount whose summit has been leveled and later submerged, leaving a broad, relatively flat top below sea level. Ogasawara Guyot has volcanic origins and is associated with Cretaceous-age geological history. It is a feature studied through marine geology and seafloor mapping, not an inhabited island or above-water landform.

Where is Ogasawara Guyot located?
Ogasawara Guyot is in the western Pacific near the Ogasawara Islands, also known as the Bonin Islands. It is a submerged submarine mountain.

Its summit is broad and relatively flat rather than sharply pointed. That shape indicates a seamount whose top was leveled before it became submerged.
