If you had “Underwater Volcano Eruption” on your 2025 Bingo Card, you just might be a winner! 

The Axial Seamount is the most active submarine volcano in its northeasterly swath of the Pacific Ocean, according the dedicated seamount blog. It sits on the Juan de Fuca ridge, about 300 miles (483 kilometers) west of the Oregon coast. And based on recent observations, the deep-sea volcano is fit to burst for the first time since 2015. 

Scientists first studied the volcano in the late 1970s, which is known to have erupted three times, in 1998, 2011, and 2015. The key piece of data in predicting a volcanic eruption is knowing the degree to which the seamount is inflated—a sign that magma has built up beneath the surface, swelling the structure’s aboveground features.

The scientists stated that Axial has re-inflated to more than 95% its threshold before the 2015 eruption—a major indicator that an eruption is somewhere around the corner.

If the 2015 eruption is any indicator, the predicted eruption could be accompanied by thousands of earthquakes and a seafloor drop of nearly 8 feet (2.4 meters). The seafloor drops because magma is ejected from the swollen volcano into the ocean. Once that is done, magma begins to slowly refill the mount, starting the whole process over again.
