Stay Informed: The Pacific Northwest’s Most Active Volcano Could Erupt Soon – What You Need to Know!

Have you ever heard of Axial Seamount? It’s a fascinating underwater volcano located about 300 miles off the coast of the continental U.S., sitting nearly a mile beneath the ocean’s surface. Unlike the more famous Yellowstone, this volcano is part of an active chain – the Cobb–Eickelberg Seamounts – created by a geological phenomenon known as a volcanic hotspot. As tectonic plates shift, they create a line of volcanoes, with Axial Seamount being the most active.

Interestingly, this volcano is right on the Juan de Fuca Ridge, where two tectonic plates interact. While one is sliding beneath the North American plate, new magma rises to form fresh seafloor. This unique positioning excites scientists. William Wilcock, a professor at the University of Washington, describes Axial Seamount as a “genuine hotspot,” noting that it rises about 3,600 feet from the ocean floor. The summit features a large caldera formed from past eruptions, a sight not commonly seen at mid-ocean ridges.

Even when it’s dormant, Axial is bustling with life. Hydrothermal vents around the volcano erupt with superheated water and nutrients, creating an unusual environment where complex ecosystems thrive. Deborah Kelley, another oceanography professor at UW, highlights how these vents act as “oases” filled with various microbes and unique marine creatures.

This year, Axial Seamount has gained attention as researchers predict it could soon erupt. At a recent conference, geophysicist William Chadwick announced that pressure levels indicate it may be primed for an eruption between now and the end of 2025. He explained that scientists gauge volcanic activity based on previous inflation patterns. Comparatively, last November, the volcano’s surface was swelling similarly to how it did before the last eruption in 2015.

While the excitement is real, forecasting eruptions isn’t straightforward. Chadwick notes that accurate predictions usually happen only hours in advance. Some signs suggest an eruption might be near, but others indicate calmness. Kelley mentioned there have been around 200 to 300 small earthquakes daily, though that’s lower than expected for an eruption forecast.

So, what can we expect if Axial does erupt? For most people, it won’t be noticeable. There won’t be tsunamis or earthquakes on land, and it poses no threat to nearby communities. Chadwick reassured that, unlike land volcanoes, forecasting undersea eruptions doesn’t involve public safety fears or evacuations.

For oceanographers, however, this would be a fascinating event. Kelly pointed out that an eruption at Axial could provide novel insights into volcanic activity, as most of Earth’s eruptions occur at mid-ocean ridges. Until it happens, much remains unknown, and every new detail can lead to important discoveries.

In studying these underwater volcanoes, scientists can gain valuable information about Earth’s geology and the dynamics of climate change. This is especially significant as we face increasing environmental challenges globally. Keeping track of Axial Seamount aids in understanding how underwater ecosystems respond to geological changes.
