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

No significant activity from Ahyi Seamount was detected in remote pressure sensor data or mostly clear satellite remote sensing data over the past day. The last submarine plume was observed on March 4. 

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.
