The Mount Redoubt volcano had another large eruption Saturday after being relatively quiet for nearly a week.
Radar indicated a plume of volcanic ash rose 50,000 feet into the sky, making it one of the largest eruptions since the volcano became active on March 22, said the National Weather Service.

Mount Redoubt in southern Alaska is puffing a little steam and emitting volcanic gases but still hasn't erupted.
Volcanologist Dave Schneider at the Alaska Volcano Observatory says winds and humidity made the steam more visible Monday. The plume extended several hundred feet above the crater.
Observatory seismologist Stephanie Prejean says Redoubt's ongoing earthquakes have shifted to a higher frequency, which could mean rock is breaking. She said the large amount of gases indicate new magma in the earth's crust.

The volcano unleashed a short but intense burst of seismicity yesterday, the strongest activity since Jan. 30.
Geologists with the Alaska Volcano Observatory say the strong tremors lasted only four minutes, then tapered off.

Brent Hibbert will replace the air filters in his 18 taxicabs every 50 to 100 miles if the volcano at Alaska's Mount Redoubt erupts and coats his hometown of Kenai with engine-choking ash.
He and other residents are preparing for what geologists say could be imminent. Steam and tremors emanating from the 10,200-foot Redoubt Volcano, located about 100 miles southwest of Anchorage, are more likely than not to result in an eruption.

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.
