Antarctica Erupts!

 

 

 

Dec 06 - Mount Erebus, a volcano in Antarctica, constantly sputters hot

gas and lava, sculpting surreal caves and hundreds of ice towers, called fumaroles.

 

Most volcanoes have a deep central chamber of molten rock capped by cool,

solid rock making the hot magma inaccessible. On Mount Erebus, the magma is

exposed at the top of the volcano, in a churning 1,700-degree Fahrenheit lake

perhaps miles deep.

 

Mount Erebus started erupting several times a day in 2005, each time ejecting

50 or so lava bombs. The largest are about ten feet wide—great blobs of bubbly

lava that collapse like failed soufflés when they land, some almost a mile away.
