Description: From Cameron and others (2020): "AVO received a report of steam coming from Korovin Volcano on February 2, 2016, from an Atka, Alaska, resident (fig. 39). A check on seismic data revealed no evidence of any increased activity, and the steaming source was from an area near the volcano with known fumarolic vents that often steam (Motyka and others, 1993). Thus, the February report is considered part of typical Korovin Volcano activity. From April through August, multiple tremor bursts were noted in the seismograph data (fig. 40), and April and May recorded more tremor bursts than the later months. AVO kept the Aviation Color Code and Volcano Alert Level GREEN and NORMAL, respectively, for Korovin Volcano but maintained increased awareness and data checks during periods of increased tremor."
