A large submarine volcano in the Pacific Ocean, hundreds of miles from the Oregon coast shows signs of an impending explosion, scientists say.

The submarine volcano, known as Axial Seamount, is nearly 1 mile (1.4 kilometers) in a hot geological point. The Axial Seamount is also located on the Juan de Fuca ridge – an area where two huge tectonic plates (the Pacific and Juan de Fuca slabs) are constantly spreading, causing a steady pressure accumulation, as CNN reports.

The incidence of earthquakes has recently increased dramatically, as the volcano creates bloating with more and more magma, signaling that an explosion could be near, according to researchers at the Ocean Observatories Initiative Regional Cabled Array of the National Science Foundation, a unit operating by the university Axial Seamount.

“Right now, there are a few hundred earthquakes a day, but they are even less than we saw before the previous explosion,” said William Wilcock, a marine geophysicist and professor at the Oceanography School of the University of Washington.

“I would say that it was going to explode sometime later (this year) or at the beginning of 2026, but it could also be tomorrow, because it is completely unpredictable,” he said.

According to CNN, the three previous explosions – in 1998, 2011 and 2015 – were noted between January and April at the time of the year when the Earth moves away from the sun.
