Distant undersea volcano believed to be erupting in Pacific Ocean

HONOLULU — A volcano might be erupting deep beneath the Pacific Ocean within the U.S. Commonwealth of the Northern Mariana Islands, however scientists don’t know for certain as a result of it’s so inaccessible.

All indications are that the Ahyi Seamount started erupting in mid-October, the U.S. Geological Survey stated Monday. The Northern Marianas are about 3,800 miles west of Honolulu.

Scientists want to see if the exercise is shallow earthquakes or if materials exploded from the crater, stated Matt Haney, a USGS analysis geophysicist. Scientists are checking satellite tv for pc knowledge to see if there’s discolored water, which may recommend materials is popping out of the volcano, he stated.

“There’s nothing proper now that implies that this eruption will intensify and change into a big eruption,” Haney stated.

Nonetheless, mariners would need to keep away from the instant space, he stated.

The Ahyi Seamount is considered one of a protracted string of submarine seamounts on the northern fringe of the Northern Mariana Islands.NOAA

Exercise from an undersea volcanic supply was picked up final month by hydroacoustic sensors some 1,400 miles away at Wake Island.

With assist from the the Laboratoire de Geophysique in Tahiti and knowledge from seismic stations in Guam and Japan, scientists analyzed the alerts to find out the supply of the exercise was in all probability Ahyi Seamount, the USGS stated in an announcement.

Exercise has been declining in latest days, the assertion stated.

Ahyi seamount is a big conical submarine volcano. Its highest level is 259 ft under the floor of the ocean. It’s positioned about 11 miles southeast of the island of Farallon de Pajaros, often known as Uracas.

“There are not any native monitoring stations close to Ahyi Seamount, which limits our skill to detect and characterize volcanic unrest there,” the company stated. “We’ll proceed to observe out there distant hydrophonic, seismic, and satellite tv for pc knowledge intently.”

The seamount is a part of the Mariana Volcanic Arc, which is a series of greater than 60 lively volcanoes stretching over 600 miles west of and parallel to the Mariana Trench, the world’s deepest level.
