Undersea volcano near Mariana Trench is believed to be erupting, say scientists

A volcano is likely erupting deep beneath the Pacific Ocean in the US Commonwealth of the Northern Mariana Islands, though scientists are unable to confirm it due to the location’s inaccessibility. All indications are that the Ahyi Seamount began erupting in mid-October, the US Geological Survey said on Monday.

The Northern Marianas are about 3,800 miles west of Honolulu. Scientists are looking to see if the activity is shallow earthquakes or if material exploded from the crater, said USGS research geophysicist Matt Haney.

Satellite observations show the water is discoloured, which suggests material is coming out of the volcano, he said. "There’s nothing right now that suggests that this eruption will intensify and become a large eruption," Mr Haney added.
