At the beginning of March the Alaska Volcano Observatory raised the alert level at Okmok to Volcanic Alert level Advisory and Aviation Colour Code Yellow following an increase in seismic activity, including bursts of volcanic tremor. Since then activity levels have fallen and remained low, and yesterday came news that the AVO has lowered alert levels once again to the non-eruptive state of Volcanic Alert Level Normal and Aviation Colour Alert Green.
