In the Himalayas, up to 500 meters is used as a criterion. In the European Alps, for example, a prominence of 30 meters is considered to be the standard for the independence of a mountain. Here again, there are no uniform absolute values. The summit of the dominantly phonolitic volcano has been modified by one or two generations of caldera formation. It is the largest of three major volcanoes forming the crudely triangular Ross Island. A key part of New Zealand’s Antarctic research program, Scott Base, is also nearby on the peninsula. Mount Erebus, the world's southernmost historically active volcano, overlooks the McMurdo research station on Ross Island. For the demarcation of two connected geoformations, the topographic prominence (shoulder drop) and dominance (distance between each other) are also used. The largest Antarctic settlementMcMurdo Station, operated by the United Statesstands within sight of the volcano (about 40 kilometers or 25 miles away). Also, a mountain has an independence, so a large hill on a mountain plateau does not become a mountain itself. Mountains are usually steeper and higher. What is a mountain? There is no exact distinction between a mountain and a hill. It is the horizontal distance between two peaks.
Its slopes are covered with snow and ice, glaciers. It is the second-highest volcano in Antarctica (after Mount Sidley) and the world’s southernmost active volcano. It took 1.3 million years to develop and currently rises at a height of 12,448 feet above sea level. The "dominance" is also recorded in the classification of mountains. Mount Erebus ( /rbs/) is the world’s most southerly active volcano. The drop is the deepest cut between the peaks. McMurdo Station was operating under New Zealand Standard Time (NZST) while New Zealand was.
On the day of the Erebus disaster there was a one-hour time difference between New Zealand and McMurdo Station. NZST, the aircraft crashed into the lower slopes of Mt Erebus, killing all on board. This is the relative height to the actual base of the mountain, which can also be a foothill of a plateau. Four minutes and 42 seconds later, at 12.49 p.m. Therefore, in addition to the absolute height, the topographic "prominence" is also measured, often called the autonomous height or shoulder drop. Prominence: Relative height to surroundings A small hill on top of a large mountain would have an extremely high peak just because of its surroundings - at least if you measure it in relation to sea level.
