Beneath Antarctica’s ice sheet lies a massive surprise: 138 hidden volcanoes, forming one of the largest volcanic regions on Earth. Most are buried under kilometers of ice and completely invisible from the surface. • The volcanoes are concealed beneath thick Antarctic ice. • Identified using radar, satellite data, and geological surveys. • Some are considered potentially active. • Heat from below may influence ice melting and glacier movement. • Helps explain unusual geothermal activity under th
