Much less known is actually that Antarctica is actually additionally lot towards numerous energetic volcanoes, aspect of a substantial "volcanic district" which expands for hundreds of kilometres along the western side side of the continent. Although the volcanic district has actually been actually recognized and also researched for many years, approximately one hundred "brand-brand new" volcanoes were actually just lately uncovered underneath the ice through experts that made use of gps records and also ice-penetrating radar towards hunt for concealed heights.
