Deep under the ice sheet covering Antarctica, volcanic fire still rages, a new study shows. The movement of magma, which may signal an upcoming eruption, was spotted by tell-tale signs of ‘tremor swarms’ in the west of the frigid continent.
Antarctica features a number of volcanoes elevating above its surface, the most active and well-known being Mound Erebus. Hence there have long been suspicions that some volcanic activity is occurring under the ice as well. This is indeed so, confirms a study published on Sunday last week in the journal Nature Geoscience, and it may have an effect on global climate change.
