![]() ![]() The upper slopes of Mount Erebus are dominated by steeply dipping (about 30°) tephritic phonolite lava flows with large-scale flow levees. Lava flows of more viscous phonotephrite and trachyte erupted after the basanite. Erebus is the world's only presently erupting phonolite volcano. Slightly younger basanite and phonotephrite lavas crop out on Fang Ridge – an eroded remnant of an early Erebus volcano – and at other isolated locations on the flanks of Erebus. The oldest eruptive products consist of relatively undifferentiated and nonviscous basanite lavas that form the low broad platform shield of Erebus. The composition of the current eruptive products of Erebus are anorthoclase-porphyritic tephritic phonolite and phonolite, which are the bulk of exposed lava flow on the volcano. The bottom half of the volcano is a shield and the top half is a stratocone. Mount Erebus is classified as a polygenetic stratovolcano. The volcano was the site of the Air New Zealand Flight 901 accident, which occurred in November 1979. 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 is the second-highest volcano in Antarctica (after Mount Sidley), the highest active volcano in Antarctica, and the southernmost active volcano on Earth. Steere, who was stationed at the McMurdo Station on the Ross Island.(claimed by New Zealand as part of the Ross Dependency) The mountain has been named after a biologist, William C. The shield volcano is also a part of the Crary Mountains range. Mount Steere is the fifth tallest volcano in Antarctica. Toney who served as the Byrd Station’s scientific leader in 1957. The Toney Mountain has been named after George R. Glacial corries and parasitic vents characterize the slopes of the mountain which remains covered in ice all-year round. This shield volcano is part of Marie Byrd Land’s Kohler Range. The fourth tallest volcano in Antarctica, the Toney Mountain has an elevation of 11,792 ft. The mountain has been named after a US Antarctic Program geologist, Lawrence A. It is the third tallest volcanic summit in the frozen continent. The 12,057 ft tall Mount Frakes is a shield volcano that is located in the Marie Byrd Land’s Crary Mountains. The first successful ascent to the summit of Mount Erebus was made in 1908. ![]() The mountain was discovered in 1841 by Sir James Clark Ross and named after one of his ships. An observatory based on the mountain collects valuable data regarding the volcano. The mountain has been spewing out lava and ash for nearly 1.3 million years ago. The volcano is located on the Ross Island of Antarctica. The mountain is regarded to be the southernmost active volcano of the planet. Mount ErebusĪntarctica’s second highest mountain, Mount Erebus, rises to an elevation of 12,444 ft. Bill Atkinson from New Zealand achieved this feat. The first recorded ascent to the summit of Mount Sidley happened on January 11, 1990. Even mountaineers are more familiar with the shorter Mount Erebus than Mount Sidley. Due to its extremely remote location, the volcano is less widely known. Byrd, an American explorer discovered the volcano while flying over it in 1934. The volcano features a massive 5 km wide caldera. The snow-covered volcano is part of the Executive Committee Range that is located in the western Antarctic region of the Marie Byrd Land. It is a dormant volcano that represents the continent in the list of the Volcanic Seven Summits. The 14,058 ft tall Mount Sidley is the tallest volcano in Antarctica. Some of the tallest volcanoes in Antarctica are as follows: 1. Antarctica’s volcanoes are found on both the mainland and the islands of the continent. Antarctica has numerous islands, mountains, glaciers, ice sheets, and even volcanoes. The Southern Ocean surrounds the entire landmass. Antarctica is the southernmost continent that is located around the South Pole of the world. ![]()
