Discover Oregon’s Underwater Volcano: A Thriving Marine Life Hotspot Ready to Erupt!

An underwater volcano off the coast of Oregon, Axial Seamount, is set to erupt this year for the first time in 11 years. This exciting event could have a big impact on marine life in the region.

Located about a mile deep and 300 miles from Astoria, Oregon, Axial Seamount has erupted three times in the past 30 years, with the last eruption occurring in 2015, according to Bill Chadwick, an expert from Oregon State University. Since it’s so far from human activity, the eruption won’t directly harm us, but it will heat seawater to over 700 degrees Fahrenheit, creating conditions for vibrant marine ecosystems.

As magma rises, it creates hydrothermal vents. These vents are like underwater hot springs, rich in minerals and nutrients that support unique life forms. “The base of this ecosystem is microbes that convert chemical energy into food, which then supports a variety of marine animals,” Chadwick explains. This creates a fascinating underwater community.

When the volcano erupts, some vents may get covered by lava but will reappear later. Even though the eruption could cause small earthquakes (around 2 to 3 on the Richter scale), they are not strong enough to be dangerous. Unlike terrestrial eruptions, underwater ones produce fewer disturbances, making forecasting a challenge. Chadwick notes, “My past predictions have seen both successes and failures, making it tough to predict exactly when the eruption will happen.”

Researchers track the magma’s movement using the Ocean Observatories Initiative, funded by the National Science Foundation. This system of cables, sensors, and equipment records data in real-time, helping scientists understand these underwater geological processes better. Interestingly, 80% of volcano eruptions occur underwater, making Axial Seamount a crucial site for advancing our understanding of these events. As Chadwick points out, “Forecasting underwater eruptions is more complex since they are quieter and cause less immediate disruption.”

The Axial Seamount eruption not only showcases the incredible power of nature but also serves as a vital opportunity for scientific learning. With ongoing research, we can hopefully improve our ability to predict future volcanic activities effectively.
