AVO/USGS Volcanic Activity Notice

Volcano: Aniakchak (CAVW #1102-09-)

Current Volcano Alert Level: UNASSIGNED
Previous Volcano Alert Level: NORMAL

Current Aviation Color Code: UNASSIGNED
Previous Aviation Color Code: GREEN

Issued: Tuesday, November 17, 2009, 11:33 AM AKST (20091117/2033Z)
Source: Alaska Volcano Observatory
Notice Number: 2009/A52
Location: N 56 deg 54 min W 158 deg 12 min
Elevation: 4400 ft (1341 m)
Area: Alaska Peninsula Alaska

Volcanic Activity Summary: AVO can no longer seismically monitor the following volcanoes because of seismic station outages. As a result, AVO is unable to (1) assess whether these volcanoes may be building towards an eruption and (2) quickly confirm or dismiss reports of activity at these volcanoes.

Veniaminof
Aniakchak
Fourpeaked
Korovin

Because these volcanoes are no longer seismically monitored, they will move from volcano alert level Normal and aviation color code Green to "unassigned". They will likely remain without real-time seismic monitoring until next summer, when necessary upgrades at these and other networks will occur. As at other volcanoes without real-time seismic networks, AVO will continue to use satellite data and reports from pilots and ground observers to detect signs of eruptive activity.

Recent Observations:
[Volcanic cloud height] Unknown
[Other volcanic cloud information] Unknown
