Volcano in deep Antarctic ice sheet

volcano Live volcano is spewing magma at a depth of over a mile below a huge ice sheet. It is an unprecedented discovery which points to the possibility of a major eruption, but with totally unpredictable consequences. 

A team of seismologists led by Douglas Wiens of Washington University made the discovery after detecting a series of earthquakes of low magnitude in the West Antarctica – the type of earthquakes that often precede volcanic eruptions. The researchers ruled out the possibility that these events that were occurring at a depth of 15 to 25 miles (25-40 km) below the sub-glacial surface were caused by earthquakes of glacial ice movement or activity tectonics due to deep and long period waves.
