During the 1970's, the lava lake was observed to be about 130 m long and oval shaped, producing occasional Strombolian explosions.

There are two dishes, to both transmit and receive data. Radar altimeter installed at the crater rim of Erebus in December 2016. One area of ongoing volcanology research relates to studying the behavior of the lava lake with a variety of on-site monitoring equipment (figure 17).įigure 17. A final report was submitted to the National Science Foundation (NSF) on the past research and ideas for future research (Mattioli and LaFemina, 2016), and includes a comprehensive list of scientific publications about Erebus. The Mount Erebus Volcano Observatory closed in 2016. Researchers from New Mexico Tech, the University of Cambridge, and University College London made yearly expeditions there between 20. During the early 2000s MEVO also used infrasonic recordings to capture data on the frequency of eruptions. Between 19 as many as 10 seismic stations were recording activity at Erebus they were monitored by the Mount Erebus Volcano Observatory (MEVO) run by the New Mexico Institute of Mining and Technology (New Mexico Tech). Seismometers were initially installed by a joint project of United States, New Zealand, and Japanese scientists in 1980-1981. For most years since the 1970's, scientists have visited Erebus during the austral summer (November-February) and gathered samples, taken SO 2 and other geochemical measurements, collected GPS data, and made observations and overflights to evaluate the condition of the volcano. Observations from MODVOLC data collected from 2000 through 2016 are also discussed. Photographs from expeditions between 20 show more recent activity at the volcano.

This report briefly summarizes research activity at Mount Erebus, and volcanic activity observed since 1972. McMurdo Station is about 40 km S of the summit of Mount Erebus. On 31 December 2013, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite acquired visible near-infrared images of the western end of Ross Island in austral mid-summer.
