Scientist see holes in glacier at Alaska volcano

Geologists monitoring Mount Redoubt for signs of a possible eruption noticed that a hole in the glacier clinging to the north side of the volcano had doubled in size overnight — and now spans the length of two football fields.

Scientists with the Alaska Volcano Observatory on Friday flew close to Drift Glacier and spotted vigorous steam emitted from a hole on the mountain. By Saturday, they had confirmed the area was a fumarole, an opening in the earth that emits gases and steam, that was increasing in size at an alarming rate.

They also saw water streaming down the glacier, indicating heat from magma is reaching higher elevations of the mountain.
