A decade after its last eruption in 2015, the Axial Seamount, a submarine volcano off the Oregon coast, is showing signs of increased activity. Scientists warn that it may be on the verge of another explosive eruption.
The Axial Seamount, located about 500 miles west of Oregon, was known for its last eruption, which spewed lava onto the sea floor. According to marine geophysicist William Wilcock, the volcano is currently inflating due to built-up magma beneath the surface. This inflation can be used as a predictor for future eruptions.
Increased seismic activity, with up to 1,000 earthquakes per day, is another indicator that an eruption may be imminent. Maya Tolstoy, a marine geophysicist, notes that the volcano is under stress and the weight of the ocean pressing down on it can cause earthquakes to increase during low tide.
While underwater volcanoes create unique habitats for marine life, their eruptions can also harm the ecosystem. If an eruption occurs soon, it’s expected to produce a loud sound, which may not be as harmful to whales but could have devastating effects on other species that live in the hydrothermal vents.
The Axial Seamount is formed by a hotspot, where magma rises from the Earth’s mantle and solidifies when it comes into contact with water. Scientists are eager to study an eruption along this mountain chain, which has happened only a few times before, leaving many unanswered questions about volcanic activity at mid-ocean spreading centers.
The potential for another explosive eruption raises concerns for Pacific Ocean dwellers, who will be impacted by the sudden release of magma and gases. While some species may survive, others could face significant harm due to ocean acidification and changes in their habitats.
