<P> Due to different interpretations of continental borders (geological, geographical, geopolitical) several definitions for the highest summits per continent and the number of continents are possible . The number of seven continents used here is based on the continent model used in Western Europe and the United States . The continents as defined here are on a geological and geographical basis, not geopolitical . </P> <P> An additional complication in determining the highest volcanic summits is defining exactly what constitutes a volcano and how much topographic prominence it must have relative to any nearby non-volcanic peaks in order to qualify . For the purposes of this list, the summits must be an actual eruptive volcanic center, not merely made of volcanic rocks which were uplifted by other geological processes . In addition, a topographic prominence of at least 1,000 feet (300 m) is required, so that the list includes only genuine volcanic mountains and not minor outpourings of lava which happened to leak to the Earth's surface in high - altitude regions (see Asia below). </P> <P> No serious dispute exists as to the highest volcanoes in Africa, North America, and Antarctica ---respectively, Kilimanjaro, Pico de Orizaba, and Mount Sidley . </P> <P> Although there are a few minor and inactive volcanoes on the Australian mainland, this list recognizes that the island of New Guinea is part of the Australian continent . Numerous scientific papers written in the 1970s and 1980s confirm that Mount Giluwe in Papua New Guinea is in fact an old eroded volcano, unlike the higher mountains of New Guinea which are all non-volcanic in origin . </P>
