The volcano that built the island's basement is inferred to be mid-plate hotspot volcanism, and was formed when a disturbance in the transition zone led magma from the zone toward Earth's surface. [ 1 ] [ 2 ] [ 3 ] Eolian limestone and hills dominates much of the surface geology of Bermuda, interbedded with layers of paleosols .

The Bermuda Pedestal is an oval geological feature in the northern Atlantic Ocean containing the topographic highs of the Bermuda Platform, the Plantagenet (Argus) Bank, and the Challenger Bank. The pedestal is 50 km (31 mi) long and 25 km (16 mi) wide at the 100 fathom line (-185 m), while the base measures 130 km by 80 km at -4200 m.
Submarine volcanoes are underwater vents or fissures in the Earth's surface from which magma can erupt. Many submarine volcanoes are located near areas of tectonic plate formation, known as mid-ocean ridges. The volcanoes at mid-ocean ridges alone are estimated to account for 75% of the magma output on Earth. [1]

The Bear Seamount is the first guyot in a chain of about 30 extinct volcanoes extending in a straight line south-eastwards from the edge of the continental shelf near Woods Hole, Massachusetts to north-east of Bermuda. These seamounts resulted from the movement of a mantle plume hotspot. This hotspot is now under the Great Meteor Seamount.
The unnamed undersea volcano, located about 1 kilometer (half a mile) off the southern coast of Iwo Jima, which Japan calls Ioto, started its latest series of eruptions on Oct. 21.
