AVO VOLCANO ACTIVITY NOTIFICATION
(1) VOLCANO OBSERVATORY NOTICE FOR AVIATION (VONA)
(2) Issued: (20170122/2331Z)
(3) Volcano: Bogoslof (VNUM #311300)
(4) Current Color Code: ORANGE
(5) Previous Color Code: ORANGE
(6) Source: Alaska Volcano Observatory
(7) Notice Number: 2017/A62
(8) Volcano Location: N 53 deg 55 min W 168 deg 2 min
(9) Area: Aleutians
(10) Summit Elevation: 492 ft (150 m)
(11) Volcanic Activity Summary: Several lightning strikes north of Bogoslof suggest that an eruption occurred around 14:09 AKST (23:09 UTC). High winds due to a storm in the area are hindering our ability to detect the eruption in seismic data. No volcanic cloud visible in satellite data at this time. We will put out more information as it becomes available.

AVO has no ground-based volcano monitoring equipment on Bogoslof volcano. We continue to monitor satellite images, data from distant seismic and infrasound instruments, and information from the Worldwide Lightning Location Network for indications of significant activity.
