An eruption at Egon on 6 February at 0103 led DVGHM to raise the Alert Level to 4 (the highest level) on the following day. The eruption was preceded by an increase in tremor, and consisted of the ejection of "glowing lava" and lapilli-sized material deposited on the volcano's S flank. An eruption occurred on 7 February at 1302 that was similar in size to the 6 February eruption.

Strong volcanic activity at Egon beginning on 3 September led DVGHM to raise the Alert Level from 3 to 4 (on a scale of 1-4) on 4 September. The increase in volcanic activity began on 27 August when plumes rose to ~300 m above the volcano and explosion earthquakes were recorded. This activity prompted DVGHM to raise the Alert Level from 2 to 3.
