According to satellite data, a small eruption of the volcano occurred. According to seismic data, two eruptive events occurred from 14:27 till 14:48 UTC and from 15:10 till 16:30 UTC on October 14. Amplitude of volcanic tremor at the start of the eruption was about 7.0 mkm. According to satellite data, ash plumes extended >100 km (62 mi) to the south-east from the volcano. A thermal anomaly over the lava dome was very intense the last several days. This is possibly the start of a strong eruption of Bezymianny volcano. KVERT continues to monitor this volcano.
