A large submarine volcano may be erupting beneath the Pacific Ocean.
Scientists are unsure if the Ahyi Seamount can be reached, however.
The volcano is located in the U.S. Commonwealth of the Northern Mariana Islands. According to the U.S. Geological Survey, all indications point towards the volcano erupting in mid-October after hydroacoustic sensors on Wake Island started recording signals consistent with such activity.
Researchers in Tahiti collaborated with us to analyze the signals and combine them with data from Japan’s seismic stations. This suggests that activity is coming from Ahyi Seamount.
Satellite imagery taken Nov. 6 shows discoloration at the volcano’s site on the ocean surface. During previous periods of activity, water discoloration was observed above the submarine volcano.
Although hydroacoustic signals continue to be detected, they have decreased in frequency over the past few days.
According to the United States Geological Survey, there is no evidence that the eruption could intensify. Mariners should stay away from the immediate area.
However, there are no monitoring stations near Ahyi Seamount, which limits our ability to detect and characterize volcanic activity there.
Scientists will continue to closely monitor remote hydro phonic and seismic data.
Ahyi Seamount, a conical volcano rising to 259 feet above the sea surface, is considerable.
The Northern Marianas lies approximately 3,800 miles west of Honolulu.
The Mariana Volcanic Arc is a group of more than 60 active volcanoes that runs over 600 miles parallel to the Mariana Trench. This is the deepest point in the world.
