Historical Significance On November 28, 1979, an Air New Zealand flight crashed on Mt. NASA's Dante Eight-legged NASA robot descended 700 feet into the crater to sample the molten lava lake Erebus's crater simulates the environment on the Moon and Mars This flight was supposed to leave Auckland. 1 2 Air New Zealand had been operating scheduled Antarctic sightseeing flights since 1977. Establish a GPS base network to monitor the deformation of the volcano The Mount Erebus disaster occurred on 28 November 1979 when Air New Zealand Flight 901 (TE-901) nb 1 flew into Mount Erebus on Ross Island, Antarctica, killing all 237 passengers and 20 crew on board.Monitor SO2 flux and CO2 emissions from the lava lake.Use Argon-argon (40Ar/39Ar) radiometric dating determine the geochronology of summit and flank lava flows.Use seismometers to understand the "plumbing" of Erebus.Geophysical Monitoring Mount Erebus Volcano Observatory, run by the New Mexico Institute of Mining and Technology McMurdo Station, operated by the United States CURRENT RESEARCH: These contribute to acid rain and the warming of the atmosphere.Emits chlorine compounds, carbon dioxide, sulfur dioxide, sulfric acid, chromium oxide, and nitrogen compounds.Seismic and acoustic observations at Mount Erebus Volcano, Ross Island, Antarctica, 19941998. Rowe CA, Aster RC, Kyle PR, Dibble RR, Schlue JW. It began to form about 1.3 million years ago and today stands 3,794m above sea level.

The volcano was erupting when British explorer Captain James Ross first observed it 1841, and it has shown continuous lava lake activity since 1972.

Erebus is a stratovolcano composed of alternating layers of solidified ash, hardened lava, and rocks ejected by earlier eruptions. This Mount Erebus image shows a fairly typical level of activity for the volcano, including a molten lava lake and vapor emissions. Since that time, EO-1 has been successfully employed to detect other volcanic eruptions, including those near densely populated areas. Scientists who subsequently examined the data EO-1 acquired confirmed that a genuine thermal emission had been detected. After the initial detection, the satellite gave itself new orders to take fresh observations of the volcano several hours later. On May 7, 2004, the Autonomous Sciencecraft Experiment on EO-1 first demonstrated its ability to detect volcanic activity by sensing thermal emissions at Erebus. The larger image shows a true-color, photo-like view of the volcano, and the inset image shows thermal activity, highlighting the volcano’s molten lava lake. The larger image was acquired by the Advanced Land Imager (ALI), and the inset image was acquired by the Hyperion sensor. This image shows two views of Mount Erebus from February 6, 2009, captured by sensors on NASA’s Earth Observing-1 (EO-1) satellite. In 2004, the reliable presence of a lava lake at this volcano’s summit made Mount Erebus the perfect place to test a self-directed satellite and sensor. The world’s southernmost volcano to show activity during recorded history, Erebus holds a lava lake and occasionally experiences explosive eruptions. Antarctica’s Mount Erebus may be covered with glaciers, but they do little to cool the volcano’s molten core.
