Image Collection | Types and Features | Submarine Volcanoes
There are 5,976 volcano images available on the GVP website, including 4,240 in these new galleries with updated captions and keywords, and at a larger size.
Most submarine eruptions are too deep to impact the surface, but shallow activity can result in explosive lava-water interactions resulting in the ejection of wet volcanic material called cocks-tail jets, and pyroclastic surges traveling across the water. Submarine eruptions can result in pumice rafts – large areas of floating pumice that travel across oceans. These eruptions can also produce features like pillow, lobate, or sheet lavas, hyaloclastites (from fragmentation of lava), and black smokers (hydrothermal vents). Hazards include steam explosions, ballistic ejecta, pyroclastic surge (a type of pyroclastic flow), and ashfall.
