Axial Seamount: The Underwater Volcano Poised to Erupt in 2025
Deep beneath the waves of the Northeast Pacific, approximately 480 kilometers (300 miles) off the coast of Oregon, the Earth is stirring.Axial Seamount, the most active underwater volcano in the region, is showing signs of an impending eruption. Scientists predict this event will occur before the end of 2025, marking the fourth eruption of the seamount in the last three decades.
“Axial is the most active volcano in the Northeast Pacific, which maybe some people don’t know, as it’s hidden under the ocean,” volcanologist Bill Chadwick explained in a recent interview with Jenn chávezin on the Oregon Public Broadcasting podcast. This submerged giant, formed from thin lava flows, is a shield volcano, meaning its eruptions are characterized by magma oozing out rather than explosive activity. This makes it unlikely to produce dramatic events like tsunamis, offering some reassurance to coastal communities.

Axial Seamount has erupted three times in the past 30 years—in 1998,2011,and most recently in 2015. Researchers have been monitoring the volcano as 1997, and their observations reveal a pattern of inflation caused by rising magma.The seamount has now reached the same level of inflation that preceded its 2015 eruption, signaling that another event is imminent.
The swelling of the volcano is a result of magma pressure forcing the seafloor to uplift. This process has been accompanied by a critically important increase in seismic activity. In recent months, the number of earthquakes in the vicinity has soared into the hundreds per day, a clear indicator of the volcano’s restlessness.
Monitoring the Unseen
While Axial seamount’s eruptions pose little threat to humans,they provide valuable insights into volcanic behavior.”It can’t do this forever,” Chadwick and his colleague, University of North Carolina geophysicist Scott Nooner, noted in a blog post. their research highlights the importance of monitoring underwater volcanoes to better predict more perilous volcanic events on land.
The seamount’s location, nestled among tectonic plates, makes it a hotspot for geological activity.Its eruptions not only reshape the seafloor but also contribute to our understanding of how magma moves beneath the Earth’s surface.
What to Expect in 2025
When Axial Seamount erupts, it will likely crack open at the surface, allowing magma to flow out and create new seafloor. This process, while dramatic, is expected to be relatively benign. Scientists will continue to monitor the volcano closely, using data from seismic activity and seafloor uplift to refine their predictions.

Unlocking the Secrets of Axial Seamount: A Deep Dive into Its Magma Plumbing System
Axial Seamount, an underwater volcano located where the Juan de Fuca tectonic plate meets the Pacific plate, has long fascinated scientists. A recent study published in Nature sheds new light on its complex magma plumbing system, offering insights that could revolutionize our understanding of volcanic activity worldwide.
The Asymmetric Magma Reservoirs
Using seismic data, researchers identified multiple magma reservoirs beneath Axial Seamount. These reservoirs are asymmetrically positioned in Earth’s upper crust, nestled beneath layers of basalt and gabbro—coarse, magnesium, and iron-rich rocks. The study, led by geophysicist Jidong Yang from the China University of Petroleum, reveals a connection between the main magma reservoir and the eruptive fissures on the seafloor.
However, the exact mechanism linking the high-melt zone to the concentration of eruptive fissures near the eastern caldera wall during eruptions in 1998, 2011, and 2015 remains a mystery.”The reason for the connection between the high-melt zone and the focusing of eruptive fissures near the eastern caldera wall in 1998, 2011, and 2015 remains unclear,” Yang and colleagues write in their paper.
A Unique Geological Setting
Axial Seamount sits at a dynamic intersection where seafloor spreading occurs. As the Juan de Fuca and Pacific plates collide, fresh ocean crust is ejected, creating a bulging seam that gradually spreads outward. This process makes Axial Seamount an ideal natural laboratory for studying volcanic activity.
The volcano’s asymmetric magma plumbing system, illustrated in a detailed diagram, highlights the complexity of its underground structure. Researchers hope that understanding this system will provide valuable lessons for studying volcanoes globally.
Implications for Global Volcanology
The findings from Axial Seamount could have far-reaching implications. “We’re hoping the lessons we learn here can be applied to volcanoes worldwide,” says Chadwick, one of the study’s contributors. By unraveling the mysteries of this underwater volcano, scientists aim to improve volcanic monitoring and eruption prediction techniques.

Q&A with Dr. jidong Yang
Editor: Dr. Yang, your research at Axial Seamount has revolutionized our understanding of magma plumbing systems. Can you explain the significance of your findings?
Dr. Yang: Absolutely.Axial Seamount is an extraordinary site due to its location at the intersection of the Juan de Fuca and Pacific tectonic plates. Our study revealed that the magma reservoirs beneath the seamount are asymmetrically positioned, which was unexpected. These reservoirs are nestled under layers of basalt and gabbro, providing a unique geological setting for study. Understanding this asymmetric arrangement helps us grasp how magma moves beneath the Earth’s surface, which can be applied to other volcanoes globally.
Editor: Axial Semount’s magma plumbing system seems quite complex. How does this system influence its eruption patterns?
Dr. Yang: Indeed, the plumbing system is intricate. We identified multiple magma reservoirs, some of which are linked to the eruptive fissures on the seafloor. During eruptions, magma travels through these fissures, frequently enough concentrating near the eastern caldera wall. Though, the exact mechanism connecting the high-melt zone to these fissures remains unclear, and this is a focus of our ongoing research.
Editor: With your research suggesting an eruption by 2025, what should we expect when it happens?
Dr.Yang: Based on our data, an eruption will likely involve the cracking open of the seafloor, allowing magma to flow out and create new oceanic crust. While dramatic, it’s expected to be relatively benign due to the seamount’s underwater location. Monitoring seismic activity and seafloor uplift has been crucial in predicting this event. Though, the timing and exact nature of the eruption still pose challenges.
Editor: Your study has implications beyond Axial Seamount. How do these findings contribute to global volcanic research?
Dr. Yang: The lessons learned here are invaluable. By understanding the magma plumbing system at Axial, we can improve our models for volcanic activity worldwide. This enhances our ability to monitor and predict eruptions on land, potentially saving lives and property. The geological features of Axial Seamount provide a natural laboratory that offers insights applicable to volcanoes in diverse environments.
Dr. Yang: Our next steps involve refining our models to better understand the magma pathways and eruption mechanisms at Axial Seamount. We’re also exploring how these findings can be integrated into broader volcanic monitoring systems globally. For aspiring geophysicists, I’d say the field is full of exciting challenges and opportunities. Volcanology is not just about studying eruptions but understanding the dynamic processes shaping our planet. Stay curious, and keep exploring!
Conclusion
Dr. Jidong Yang’s research at Axial Seamount provides a fascinating glimpse into the world of underwater volcanoes. His findings on the asymmetric magma reservoirs and their connection to eruptive fissures offer valuable insights that could revolutionize volcanic monitoring and prediction.
