Much of its bulk remains underwater; [21] its subaerial surface is a gently sloping, elongate, decentralized shield with a surface area of approximately 1,500 km 2 (579 sq mi), [26] making up 13.7 percent of the island's total surface area. [16] Kīlauea lacks topographical prominence, appearing only as a bulge on the southeastern flank of ...
This is a list of tectonic plates on Earth's surface. ... New Hebrides plate – Minor Pacific Ocean tectonic plate – 1,100,000 km 2 (420,000 sq mi)
Obduction zones occurs when the continental plate is pushed under the oceanic plate, but this is unusual as the relative densities of the tectonic plates favours subduction of the oceanic plate. This causes the oceanic plate to buckle and usually results in a new mid-ocean ridge forming and turning the obduction into subduction. [citation needed]
Further subsidence causes the volcano to sink below the sea surface, becoming a seamount. Once a seamount is 600 m (2,000 ft) or more under the surface, it is also classed as a guyot . [ failed verification ] [ 1 ] This list documents the most significant volcanoes in the chain, ordered by distance from the hotspot, but there are many others ...
The Kīlauea Caldera (Hawaiian: Kaluapele [2]), officially gazetted as Kīlauea Crater, is a caldera located at the summit of Kīlauea, an active shield volcano in the Hawaiian Islands. It has an extreme length of 2.93 mi (4.72 km), an extreme width of 1.95 mi (3.14 km), a circumference of 7.85 mi (12.63 km) and an area of 4.14 sq mi (10.7 km 2 ...
