NORTHERN MARIANA ISLANDS VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Thursday, June 1, 2023, 9:12 AM ChST (Wednesday, May 31, 2023, 23:12 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 volcanic activity was observed in cloudy satellite images of the sea surface around Ahyi Seamount, and no signficant earthquakes were located from distant seismic stations.

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.
