How much melting in Antartica is due to volcanic activity???

Earthquakes deep below West Antarctica reveal an active volcano hidden beneath the massive ice sheet, researchers said today (Nov. 17) in a study published in the journal Nature Geoscience

he discovery finally confirms long-held suspicions of volcanic activity concealed by the vast West Antarctic Ice Sheet. Several volcanoes poke up along the Antarctic coast and its offshore islands, such as Mount Erebus, but this is the first time anyone has caught magma in action far from the coast.

“This is really the golden age of discovery of the Antarctic continent,” said Richard Aster, a co-author of the study and a seismologist at Colorado State University. “I think there’s no question that there are more volcanic surprises beneath the ice.”
