Stunning footage has revealed a rare underwater ‘volcano’ erupting off the coast of Taiwan. As the drone flies over the around Kueishantao Island, off the coast of Taiwan’s Gueishan Island, beautiful bubble plumes can be seen surfacing as volcanic vents erupt underwater. The video was captured by marine scientist Mario Lebrato, 29, from Spain. Mario, who works at the University of Kiel in Germany, said: ‘We were diving to obtain volcanic sulphur, [but] shot an aerial video to explore the area.

‘Will there be a new eruption soon? Only time will tell.’ Kueishantao Island, reaches 1315ft (401m) above sea level at its peak, and is the southernmost of five small volcanic islands off the north-east coast of Taiwan. The island is also known as ‘Turtle Mountain Island’ thanks to its profile as seen from some points on mainland Taiwan. Historical accounts during the time of King Qianlong of the Qing Dynasty (1775-1795 AD) documented the Guieshan mountain splitting open with a blood-red lava flow. Today, Kueishantao displays vigorous active submarine fumaroles and solfataras that discolor seawater over wide areas. A fumarole is an opening in a planet’s crust, usually close to a volcano, which emits steam and gases such as carbon dioxide, sulphur dioxide, hydrogen chloride, and hydrogen sulphide. A solfataras is a volcanic vent emitting sulphurous gases and water vapour or sometimes hot mud. MORE
