Quivers in the remote West Antarctic have all the hallmarks of volcanoes and magma under the ice, according to a study appearing November 17 in Nature Geoscience.
Volcanic activity in the continent’s crust could hasten the flow of its ice sheet to the ocean, scientists say.
Using 37 seismic stations, earth scientist Amanda Lough of Washington University in St. Louis and colleagues recorded hundreds of rumbles on the frozen continent in 2010 and 2011. The tremors’ frequencies and depths – betw...
