Current Level of Concern Color Code: ORANGE
Previous Level of Concern Color Code: RED
The level of earthquake activity at Augustine Volcano has diminished significantly since the last explosive event on 07:58 AST (1658 UTC), January 17, 2006. AVO is therefore lowering the color code at Augustine Volcano from RED to ORANGE.
The level of seismic activity at the volcano remains above background. Based on patterns of volcanic eruptions in 1976, 1986, and current activity, it is likely, but not certain, that further explosive activity will occur. Explosive events similar to those of January 13, 14, and 17 could occur with little or no warning. AVO will continue 24/7 staffing and will be monitoring activity closely.
An observation flight on the afternoon of January 17 noted a brown ashy haze lingering over the island. Occasional views through the haze showed that most of the lava dome that formed following the January 14 eruption was destroyed in the explosion of January 17. Another overflight is planned for today.
ABBREVIATED COLOR CODE KEY
(contact AVO for complete description):
GREEN volcano is dormant; normal seismicity and fumarolic activity occurring
