Ahyi volcano (Mariana Islands, USA) - Smithsonian / USGS Weekly Volcanic Activity Report for 9 November-15 November 2022 (New Activity / Unrest)
Wed, 16 Nov 2022, 15:00 15:00 PM | BY: VN
On 15 November the USGS reported that hydroacoustic sensors at Wake Island began to record signals in mid-October that are consistent with submarine volcanic activity. A combined analysis of the hydroacoustic signals and seismic data from stations on Guam and Chichijima Island, Japan, suggest the source of this activity is at or near Ahyi seamount. Contrary to initial observations of there being discoloration on the water's surface, a reanalysis of satellite imagery from 6 November showed no evidence of water discoloration at the ocean surface.Source: Emergency Management Office of the Commonwealth of the Mariana Islands and United States Geological Survey Volcano Hazards Program
