According to the Messner list, Puncak Mandala (4,760 m) on New Guinea is the second highest of the Australian continent. Heights of mountain peaks in West Papua are poorly established, and Puncak Trikora has been listed as the second-highest summit on the island, but SRTM data do support a higher elevation for Mandala. Both lists count Mount Elbrus as the highest peak in Europe. This makes Dykh-Tau (5,205 m), located in Russia, the second-highest summit in
Volcanic Seven Summits of these cones have a prominence greater than . The volcanoes in the list below all have prominences far exceeding that threshold. "NOTE: Two of the Volcanic Seven Summits, Kilimanjaro and Elbrus, are also members of the Seven Summits. Ojos del Salado is also a member of the Seven Second Summits." Defining the second highest volcanoes on each continent is a bit more complicated, because the continental definitions become critical. The problem between Australia and Oceania: Mount Hagen in Papua New Guinea is certainly the second highest volcano on the Australian continent, but expanding the continental definition to span also
