The southernmost active volcano on Earth is in Antarctica. It spews crystals and is very close to the U.S. Research Center.
Mount Erebus is the second-highest volcano in Antarctica (after Mount Sidley) and the southernmost active volcano on Earth. It is the sixth-highest ultra mountain on the continent. With a summit elevation of 3,794 meters (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.
The volcano has been active since about 1.3 million years ago and is the site of the Mount Erebus Volcano Observatory run by the New Mexico Institute of Mining and Technology.
The volcano was the site of the Air New Zealand Flight 901 accident, which occurred in November 1979.
