Geologists did a fly over the sight said the could smell sulfur in the air so staff at the observatory will be monitoring activity and satellite images that identify temperature changes round the clock.
If Redoubt erupts, it will likely dump ash on several surrounding communities including Anchorage, Alaska.
The last time Mount Redoubt erupted was in December 1989 and lasted for five months causing mud flows into the Drift River drainage which caused partial flooding of the Drift River Oil Terminal facility. The large ash plume also disrupted international air traffic and a thin ash layer coated Anchorage and surrounding communities.
Below is an image of the eruption in 1990 of Mount Redoubt.
