Ukinrek Maars Activity - Color Code UNASSIGNED Alert Level UNASSIGNED

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.

Ugashik-Peulik
Ukinrek Maars
Little Sitkin

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