Scientists predict underwater volcano eruption 300 miles off Oregon
An underwater volcano off the Oregon coast could erupt late this year, scientists say. The volcano, known as Axial Seamount, is more than 4,900 feet beneath the Pacific Ocean and 300 miles off the Oregon coast, but it is showing signs it will soon erupt for the first time since 2015. The volcano is formed by a hot spot, an area in the Earth's mantle where hot plumes of molten material rise upward into the crust, the University of Washington's College of the Environment said in an April blog post. As the crust moves over the top of the mantle, the hot spot stays put, which results in long chains of volcanoes over time.

"Axial Seamount is a direct result of these fundamental processes that continue to shape our planet today." The eruption doesn't pose a danger, scientists said. Read On The Fox News App "Axial Seamount is much too deep and far from shore for people on land to even notice when it erupts. An eruption at Axial Seamount also has nothing to do with seismic activity on land, so Pacific Northwesterners don't need to worry about this event triggering a major earthquake or tsunami," the blog post states. The first sign of an eruption at the volcano will be a sharp increase in the number of earthquakes around it, the post states. Video: Water Cascades Down Side Of Building In Bangkok Following Earthquake "The volcano has already surpassed the inflation we observed in 2015, but the earthquake activity is still quite low," said Deborah Kelley, a professor at the UW School of Oceanography and director of the Regional Cabled Array. "We're seeing 200 to 300 earthquakes per day, with some spikes around 1,000 per day due to the tides. If what we learned in 2015 is correct, I would expect to see more than 2,000 per day for a few months before the eruption." The quakes will be caused by magma moving toward the surface, the post states. "That period lasts about an hour, and then the magma reaches the surface," said William Wilcock, a professor at the UW School of Oceanography. "Lava flows spread across the caldera, and lava-filled fissures open up to the north or the south, reaching as far as 40 kilometers (about 25 miles). "The seismic activity dies down pretty quickly over the next few days, but the eruption will continue slowly for about a month."Original article source: Scientists predict underwater volcano eruption 300 miles off Oregon

Underwater volcano off West Coast could erupt later this year, scientists say
An underwater volcano off the Pacific Coast could erupt by the end of the year, according to scientists. The volcano, known as Axial Seamount, is more than 4,900 feet beneath the Pacific Ocean and 300 miles off the Oregon coast. In relation to California, it is about 700 miles northwest of San Francisco, according to the Los Angeles Times. Despite its low familiarity among the public, the submarine volcano is considered the most active in the Pacific Northwest. Scientists say the looming eruption will offer an unprecedented glimpse into Earth-shaping processes that are usually hidden deep beneath the waves. 'Over two-thirds of the Earth's surface was formed by volcanic eruptions at these mid-ocean ridges,' Maya Tolstoy, a marine geophysicist and dean of the University of Washington's College of the Environment, said in a university blog post. 'Axial Seamount is a direct result of these fundamental processes that continue to shape our planet today.' Thankfully, scientists say the potential eruption poses no danger to residents. 'Axial Seamount is much too deep and far from shore for people on land to even notice when it erupts. An eruption at Axial Seamount also has nothing to do with seismic activity on land, so Pacific Northwesterners don't need to worry about this event triggering a major earthquake or tsunami,' the blog post stated. The volcano has erupted three times in recent years: in 1998, 2011, and 2015. The data collected from the volcano will also help scientists improve eruption forecasting for Axial Seamount and other underwater volcanoes worldwide. Instruments installed after the 2015 eruption have enabled researchers to track the volcano's behavior. Copyright 2025 Nexstar Media, Inc. All rights reserved.
