(Newser) – Alaska's Mount Redoubt has erupted again, spewing an ash cloud 50,000 feet up into the air. The Alaska Volcano Observatory in Anchorage says the volcano had a significant eruption after midnight today, and coughed up ash that is expected to move north toward the Alaska Range, missing Anchorage, which is about 100 miles from the volcano. 

The observatory says after the eruption, it detected strong seismic activity lasting 20 minutes or more followed by an hours-long low-level tremor. Since a series of eruptions began last weekend, the volcano has had about a dozen bursts. The last time the volcano erupted was during a four-month period in 1989-90.
