April 16, MAT-SU—The Alaska Volcano Observatory web site reports the following:
The 2009 eruption of Redoubt continues. Clear weather allows web cameras and satellites to view a vigorous steam plume, possibly containing minor ash, and rising up to 16,000 feet according to pilot reports. Low-level seismicity continues and a lava dome is growing in the vent.
The volcano remains at aviation color code ORANGE and alert level WATCH. The potential for renewed explosive activity is high and may resume with little warning, likely generating an ash plume and a lahar.
If conditions worsen, the MAT-SU Borough has an emergency information hotline at 761-3790, where information will be posted. A web site will post information as well.
