Report prepared by the U.S. Geological Survey.
AHYI SEAMOUNT VOLCANO (VNUM #284141)
20°25'12" N 145°1'48" E, Summit Elevation -259 ft (-79 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
Underwater pressure sensors at Wake Island continue to detect signals from the direction of Ahyi Seamount over the last day. No plumes were seen in partly cloudy satellite images since daytime images on May 22, 2023.
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.
