Satellite images were mostly cloudy, though a possible steam plume was visible during 5-6 August. ...mehrThe Volcano Alert Level remained at Watch and the Aviation Color Code remained at Orange. [ less] Sa, 6 Jul 2019, 08:26 Yesterday, the Alaska Volcano Observatory raised the alert level of the volcano due to an increase in seismicity above background levels. ...mehrThe Aviation Color Code is now YELLOW and the Alert Level of the volcano is ADVISORY. No explosive activity has been detected on infrasound data. [ less] Do, 1 Nov 2018, 23:55 AVO reports that there have been no explosions in the last day, and only two the day before. The volcano remains highly restless and explosions could resume.

Elevated seismicity continues. Mi, 3 Okt 2018, 02:56 On September 16, AVO raised the volcano to Aviation Color Code YELLOW and Volcanic Alert Level ADVISORY due to increased seismicity. The following day, activity increased further, with bursts of tremor; AVO raised the Aviation Color Code to ORANGE and Volcanic Alert Level to WATCH. Subsequent satellite imagery showed ash deposits and a new tephra cone on the northern cone of Mount Cerberus, one of the cones of the volcanic system. No significant emissions have been detected. Di, 2 Jun 2015, 11:05 A decline in seismicity over the last few months and no sign of activity in daily satellite images prompts AVO to downgrade Semisopochnoi volcano from Aviation Color Code YELLOW and Volcanic Alert Level ADVISORY to UNASSIGNED.

In addition, we have detected brief periods of seismic tremor, which can indicate movement of magma or magmatic gases. Thus we are increasing the aviation color code to YELLOW and the volcano alert level to ADVISORY."
