U.S. Geological Survey
Friday, January 19, 2024, 6:43 AM ChST (Thursday, January 18, 2024, 20:43 UTC)

Report prepared by the U.S. Geological Survey.

AHYI SEAMOUNT (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

No unusual activity observed in satellite data over the past day.  No earthquakes reported over the past day and no volcanic activity observed on underwater pressure sensors near Wake Island (1,410 miles east of Ahyi).

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.
