Scientists predict an undersea volcano eruption near Oregon in 2025
Real-time data from Axial Seamount provides a good test case for eruption forecasting
This much advance notice is a big deal, because forecasting eruptions more than hours ahead is “pretty unique,” says geophysicist William Chadwick. But 470 kilometers off the Oregon coast and over a kilometer beneath the waves, a volcano known as Axial Seamount ticks all the boxes that hint at imminent activity, Chadwick and his colleagues reported December 10 at a meeting of the American Geophysical Union in Washington, D.C.
For the past decade, a suite of devices have been monitoring Axial’s every action — rumbling, shaking, swelling, tilting — and delivering real-time data via a seafloor cable. It’s “the most well-instrumented submarine volcano on the planet,” says Mark Zumberge, a geophysicist at Scripps Institution of Oceanography in La Jolla, Calif., who was not involved in the work.
But in November, a particular milestone caught Chadwick’s eye: Axial’s surface had ballooned to nearly the same height as it had before its last eruption in 2015 — fortuitously, just months after monitoring began. Ballooning is a sign that magma has accumulated underground and is building pressure."
