|(7) Notice Number:||2017/A84|

|(11) Volcanic Activity Summary:||No new volcanic emissions have been detected from Bogoslof Volcano since the activity that began at 5:20 UTC, January 31 (20:20 AKST, January 30). No detectable activity has been observed in recent seismic, infrasound or lightning data. AVO is reducing the Aviation Color code to ORANGE and the Alert Level to WATCH. High winds in the region are being seen on seismic and infrasound stations making it difficult to detect smaller signals from Bogoslof. Significant ash-producing explosions could occur at any time, with no detectable precursors. Low-level activity below our detection limit is possible and may present a hazard in the immediate vicinity of the island.
