Ahyi Volcano Alert Level Raised To Yellow, USA
Starting at 06:35 24 April ChST (20:35 23 April UTC), seismic stations on Pagan, Sarigan, Anatahan and Saipan began recording signals believed to be from an undersea volcanic source. Hydroacoustic sensors on Wake Island suggest that the source of this seismic activity is at or near Ahyi seamount. We cannot locate precisely the source of the activity and it is possible that the vent is one of the other volcanic seamounts in the area. Seismic activity is ongoing at this time.
