|(3) Volcano:||Gareloi (VNUM #311070)|
|(4) Current Color Code:||UNASSIGNED|
|(5) Previous Color Code:||GREEN|
|(6) Source:||Alaska Volcano Observatory|
|(7) Notice Number:||2021/A107|
|(8) Volcano Location:||N 51 deg 47 min W 178 deg 47 min|
|(10) Summit Elevation:||5161 ft (1573 m)|
|(11) Volcanic Activity Summary:||Low power likely due to snow cover has resulted in loss of operation and communication with all seismic stations on Gareloi. As a result, the Alaska Volcano Observatory can no longer locate earthquakes or detect seismic signals that could indicate unrest at Gareloi volcano, and the Aviation Color Code and the Volcano Alert Level are now designated as UNASSIGNED. Seismic stations may come back online this spring as snowpack decreases.
Any eruptive activity may still be detected, although with some delay, with regional infrasound networks, detection of lightning, and monitoring of satellite images.
