Geological Background of Mount Erebus
Mount Erebus is a polygenetic stratovolcano located on Ross Island, Antarctica, and is the southernmost active volcano on Earth. It formed over 1.3 million years ago as part of the Erebus hotspot, which causes magma to rise through the Earth’s thinned crust in the West Antarctic Rift System. The volcano’s lower half is a broad shield formed by relatively fluid basanite lava flows, while the upper half is a steep stratocone composed mainly of tephritic phonolite lava flows. Its summit caldera, formed by a massive explosive eruption, hosts a persistent convecting phonolitic lava lake, one of only five long-lasting lava lakes worldwide. This lava lake has been continuously active since at least the early 1970s, producing frequent Strombolian eruptions that eject magma and volcanic bombs. The volcano’s unique geology includes anorthoclase-porphyritic lava and extensive ice fumaroles sculpted by volcanic steam interacting with the Antarctic cold. Scientific study of Erebus is facilitated by its proximity to research stations on Ross Island, making it a key site for volcanological research.
