Events of Special Interest
Redoubt Volcano Observations - Alaska
2009-05-22
The 2009 eruption of Redoubt continues. Seismicity remains low, but is above background levels. Occasional rockfalls down the steep sides of the lava dome are also continuing, often generating diffuse, low-level ash clouds at the summit.
Redoubt Volcano is a stratovolcano located within a few hundred kilometers of more than half of the population of Alaska. This volcano has erupted explosively at least six times since historical observations began in 1778. The Redoubt volcano erupted in March 2009. An eruption also occurred in 1989-90 and similar eruptions can be expected in the future. (source: Alalska Volcano Observatory)
