The volcano is scientifically remarkable in that its relatively low-level and unusually persistent eruptive activity enables long-term volcanological study of a Strombolian eruptive system very close (hundreds of metres) to the active vents, a characteristic shared with only a few volcanoes on Earth, such as Stromboli in Italy. Characteristic eruptive activity consists of Strombolian eruptions from the lava lake or from one of several subsidiary vents, all within the volcano's inner crater. The summit contains a persistent convecting phonolitic lava lake, one of five long-lasting lava lakes on Earth. It is the current eruptive centre of the Erebus hotspot. Mount Erebus is the world's southernmost active volcano. The volcano was the site of the Air New Zealand Flight 901 accident, which occurred in November 1979.Īnorthoclase crystal (45 mm long) from Mt. The volcano has been active since about 1.3 million years ago and has a long-lived lava lake in its inner summit crater that has been present since at least the early 1970s. With a summit elevation of 3,794 metres (12,448 ft), it is located in the Ross Dependency on Ross Island, which is also home to three inactive volcanoes: Mount Terror, Mount Bird, and Mount Terra Nova. It is the sixth-highest ultra mountain on the continent. Mount Erebus ( / ˈ ɛr ɪ b ə s/) is the second-highest volcano in Antarctica (after Mount Sidley), the highest active volcano in Antarctica, and the southernmost active volcano on Earth. (claimed by New Zealand as part of the Ross Dependency)
