Erebus Volcanic Province: volcanology
The Erebus Volcanic Province is the largest Neogene volcanic province in Antarctica, extending c . 450 km north–south and 170 km wide east–west. It is dominated by large central volcanoes, principally Mount Erebus, Mount Bird, Mount Terror, Mount Discovery and Mount Morning, which have sunk more tha...
