Several signals have been noted in the last two days in pressure sensors at Wake Island from the direction of Ahyi Seamount. These maybe related to underwater explosions or earthquakes at the volcano. No underwater plumes were visible in clear satellite images of the water in the region.

There are no local monitoring stations near Ahyi Seamount, which limits our ability to detect and characterize volcanic unrest there. We will continue to monitor available remote hydrophonic, seismic, and satellite data closely.
