Ahyi Volcano News

 




The Northern Mariana Islands Volcano Observatory announced that the ongoing seismic unrest at the volcano has reduced over the past four weeks.

Since late-March-mid-April, no particular and significant signs of hydroacoustic detection nor discoloured water have been registered.
Therefore, the volcano observatory declined the alert level to "Unassigned".

The activity of the undersea volcano continued to be elevated since mid-October last year as hydroacoustic sensors at Wake Island, located 2,270 km (1,410 miles) east of the volcano, began to register signals consistent with activity from the undersea volcanic source. The plume of discoloured water above Ahyi undersea volcano has been visible constantly in satellite data since 18 November.
