International research led by geologists from Curtin University has found that a volcanic province in the Indian Ocean was the world's most continuously active—erupting for 30 million years—fuelled by a constantly moving conveyor belt of magma. It's believed this magma conveyor belt, created by shifts in the seabed, continuously made space available for the molten rock to flow for millions of years, beginning around 120 million years ago. Research lead Qiang Jiang, a Ph.D. candidate from Curtin's School of Earth and Planetary Sciences, said the studied volcanoes were in the Kerguelen Plateau, located in the Indian Ocean, about 3,000 kilometers...
