Geology and volcanology

Mount Erebus is the world's southernmost active volcano. It is the current eruptive centre of the Erebus hotspot. The summit contains a persistent convecting phonolitic lava lake, one of five long-lasting

s on Earth. 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 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

Ice fumaroles

Mt. Erebus is notable for its numerous ice

The caves on Erebus are of special interest for astrobiology, as most surface caves are influenced by human activities, or by organics from the surface brought in by animals (e.g. bats and birds) or ground water. The caves at Erebus are at high altitude, yet accessible for study. Almost no chance exists of photosynthetic-based organics, or of animals in a food chain based on photosynthetic life, and no overlying soil to wash down into them. They are dynamic systems that collapse and rebuild, but persist over decades. The air inside the caves has 80 to 100% humidity, and up to 3%

Named features

Mount Erebus is large enough to have several named features on its slopes, including a number of craters and rock formations. Named craters located on Mount Erebus include Side Crater, a nearly circular crater named for its location on the side of the main summit cone, and Western Crater, named for the slope on which it sits. There are many rock formations on Mount Erebus. On the northwest upper slope of the active cone near a former exploration camp site, lava flow has formed a prominent outcropping called Nausea Knob, named for the nausea caused by elevation sickness. Also on the northwest slope sits Tarr Nunatak, named by the

Robotic exploration

In 1992, the inside of the volcano was explored by ''Dante I'', an eight legged tethered robotic explorer. ''Dante'' was designed to acquire gas samples from the magma lake inside the inner crater of Mount Erebus to understand the chemistry better through the use of the on-board gas

, as well as measuring the temperature inside the volcano and the radioactivity of the materials present in such volcanoes. ''Dante'' successfully scaled a significant portion of the crater before technical difficulties emerged with the fibre-optic cable used for communications between the walker and base station. Since ''Dante'' had not yet reached the bottom of the crater, no data of volcanic significance was recorded. The expedition proved to be highly successful in terms of robotic and computer science, and was possibly the first expedition by a robotic platform to Antarctica.

aircraft and began in February 1977. The flight crashed into Mount Erebus on November 28, 1979, killing all 257 people on board. Passenger photographs taken seconds before the collision ruled out the "flying in a cloud" theory, showing perfectly clear visibility well beneath the cloud base, with landmarks to the left and to the right of the aircraft visible. The mountain directly ahead was lit by sunlight shining from directly behind the aircraft through the cloud deck above, resulting in a lack of shadows that made Mount Erebus effectively invisible against the overcast sky beyond in a classic whiteout (more accurately, "flat-light") phenomenon.Royal Commission Report, para 40(a) Further investigation of the crash showed an Air New Zealand navigational error and a cover-up that resulted in about $100 million in lawsuits. Air New Zealand discontinued its flyovers of Antarctica. Its final flight was on February 17, 1980. During the Antarctic summer, snow melt on the flanks of Mount Erebus continually reveals debris from the crash that is visible from the air.
