In which country is Mount Giluwe the highest volcano?

The Volcanic 7 Summits are the highest volcanoes on each of the 7 continents. Mount Kilimanjaro and Mount Elbrus, which were formed volcanically, are the highest peaks of Africa and Europe respectively. They feature on the lists of both the Volcanic 7 Summits and the 7 Summits list.

Mount Giluwe in Papua New Guinea has the distinction of being its highest volcano and is one of the Volcanic 7 Summits.

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 Australasian 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.

Even if this continent is defined instead as Oceania by adding New Zealand and Polynesia including Hawaii, Giluwe remains the highest volcano since it exceeds the elevation of Mauna Kea in Hawaii and any volcano in New Zealand.

Following Mount Wilhelm, the second-highest mountain in Papua New Guinea is Mount Giluwe is at 4,367 metres (14,327 ft). It is located in the Southern Highlands province and is an old shield volcano with vast alpine grasslands. Ancient volcanic plugs form its two summits, with the central peak the highest and an east peak about 2 kilometres (1.2 mi) away at 4,300 m (14,108 ft).
