Mount Erebus volcano, Antarctica, is the world's most southerly active volcano, and presents one of the world's few examples of an open conduit system hosting a large convecting lava lake. It is classified as a polygenetic stratovolcano, and at its apex rises 3794 meters above sea level.

Current magmatism on Erebus is dominantly phonolitic, and eruptive activity, typically referred to as Strombolian in nature, manifests as large gas slug decompression and subsequent lava lake explosion. Occasional eruptions also occur from a secondary ash vent, known as Werner's fumerole, though the structural connection to the main lava lake system is currently unresolved.

Given its proximity to McMurdo station, Erebus volcano is a natural scientific laboratory and has been the subject of over 50 years of continuous interest and study. As part of a currently funded NSF initiative (NSF #1917178) awarded to scientists at UTEP, CSU, and UAF, this portal serves both as a public data resource, as well as the face of Erebus science.
