Since 27 March this year, no signs of unrest have been observed at Ahyi Seamount.
The last sighting of a discolored water plume near the seamount was recorded via satellite imagery. Moreover, underwater pressure sensors located near Wake Island (1,410 miles east of Ahyi) have not detected any significant activity during this recent period of unrest, unlike previous occurrences.
Given the apparent absence of activity and the absence of local monitoring stations near Ahyi Seamount, the Aviation Color Code and Volcano Alert Level are being downgraded to Unassigned.
