Table of Contents
off the coast of Oregon, a dramatic event is brewing beneath the waves. Axial seamount, one of the most active underwater volcanoes in the northeast Pacific, is exhibiting clear signs of an impending eruption, potentially sometime between now and the end of 2025.
Located approximately 300 miles (480 kilometers) west of Cannon Beach, Oregon, Axial Seamount has a history of regular eruptions, previously rumbling to life in 1998, 2011, and 2015. This consistent activity, however, makes it a unique subject for scientific study, allowing researchers to monitor its behaviour with unprecedented detail.
Bill Chadwick, a geophysicist at Oregon State University, paints a vivid picture of the situation: “Based on current patterns, and the assumption that Axial will be ready to erupt when it reaches the inflation (eruption) threshold in 2015, the current eruption estimate is between now (…) and the end of 2025.” His statement, delivered at the 2024 American Geophysical Union annual meeting, underscores the urgency of the situation.
A Unique Possibility for Scientific Observation
While predicting volcanic eruptions remains a challenge, Axial Seamount’s consistent behavior provides a rare opportunity for scientists. The volcano’s location on the Juan de Fuca Ridge allows for extensive monitoring. For over a decade, a sophisticated network of sensors has meticulously tracked the volcano’s every movement, recording the subtle expansion of the seafloor as magma builds, the increase in seismic activity, and ultimately, the eruption itself.
The data collected reveals a fascinating pattern. By late 2023, researchers noted a doubling of the volcano’s inflation rate. Then, in mid-2024, seismic activity surged, exceeding 500 earthquakes per day. Chadwick succinctly summarizes the implications: “This can’t happen forever.”
Mark Zumberge of the scripps Institution of Oceanography emphasizes the extraordinary monitoring capabilities deployed at Axial seamount: “This is the most well-instrumented underwater volcano on the planet.” This advanced network,including seafloor pressure sensors,autonomous underwater vehicles (auvs),and remotely operated vehicles (ROVs),provides an unparalleled level of insight into the volcano’s inner workings.
Recent studies utilizing full waveform inversion (FWI),a cutting-edge seismic technique,have produced high-resolution images of the volcano’s subsurface. These images reveal a complex system of magma reservoirs and channels, providing a detailed understanding of the magma’s movement and accumulation leading up to a potential eruption.
While the eruption’s exact timing remains uncertain, the scientific community is closely monitoring Axial Seamount, leveraging its unique characteristics to enhance our understanding of underwater volcanic activity and improve future eruption prediction models. The potential impact on the surrounding marine habitat and any potential tsunami risk are also being carefully assessed.
Axial Seamount: A Deep-Sea Volcano Poised to Erupt
Off the coast of Oregon, a dramatic event is brewing beneath the waves. Axial Seamount, an underwater volcano, is showing signs of an impending eruption, captivating scientists and offering a rare opportunity to study these powerful forces of nature up close. This underwater spectacle, while posing minimal direct threat to human life, presents a unique chance to refine eruption prediction models and understand the impact on fragile deep-sea ecosystems.
The potential for a tsunami, though unlikely, remains a consideration. The devastating 2022 eruption of the Hunga Tonga-Hunga Ha’apai volcano serves as a stark reminder of the power of underwater volcanic activity. “The 2022 eruption of the Hunga tonga underwater volcano caused $90 million in damage and left scientists struggling to understand its impact,” highlighting the need for improved predictive capabilities.
Researchers are eagerly awaiting the eruption. Rebecca Carey, a volcanologist from the University of Tasmania, emphasizes the scientific value: “Finding the eruption that occurred will provide a glimpse of its impact on the hydrothermal system and nearby biological communities,” he told Science News. These hydrothermal vents, teeming with unique life forms, offer a crucial window into how deep-sea ecosystems respond to such extreme events.
Harnessing AI for improved Predictions
Each eruption provides invaluable data for refining forecasting techniques. Scientists are now leveraging artificial intelligence to analyze seismic patterns,aiming for unprecedented accuracy in eruption predictions – potentially down to the hour. However,as researcher Chadwick notes,”Will this preliminary earthquake detection be successful?” the success of this approach coudl revolutionize volcano monitoring globally.
Beyond immediate eruption prediction, the research holds broader implications for understanding plate tectonics and oceanic crust formation. Axial Seamount sits at the intersection of the Juan de Fuca ridge and Cobb Hotspot, a region rich in magma. Studying this volcano helps scientists unravel the processes of magma accumulation, pooling, and eventual release, contributing to the growth of the ocean floor.
Lessons from the Past, Insights for the Future
The 2015 eruption of Axial seamount, releasing 156 million cubic meters of lava, provided a wealth of data. Autonomous underwater vehicle (AUV) surveys revealed lava flows extending along a 12-mile-long fissure, creating new seafloor features. These findings formed the basis for detailed maps now used to monitor current activity.
Despite advancements, predicting volcanic behavior remains challenging. Michael poland of the US Geological Survey cautions, “There’s always a risk that a volcano will follow a pattern we’ve never seen before and do something unexpected.” The key challenge lies in translating observed patterns into worldwide principles applicable to other, less predictable volcanoes worldwide.
Oregon Coast Awaits Potential Eruption of Active Underwater volcano
World-Today-News.com Senior Editor, Sarah Walker, discusses the imminent eruption of Axial Seamount with leading volcanologist Dr. Emily Carter.
Dr. Emily Carter, a volcanologist specializing in submerged volcanic activity, joins us today to shed light on the latest developments concerning Axial Seamount, a volcanic behemoth teeming with activity just off the Oregon coast.Axial Seamount, renowned for its past eruptions, is exhibiting clear signs of another perhaps explosive event in the near future.
Sarah Walker: Dr. Carter, thank you for joining us today. Could you tell our readers a little about Axial Seamount and why it’s generating so much interest right now?
Dr. Emily Carter: Absolutely. Axial seamount is a remarkable underwater volcano nestled along the Juan de Fuca Ridge,about 300 miles off the coast of Oregon. It’s incredibly active, with a history of eruptions in 1998, 2011, and most recently, in 2015. what makes it so compelling is its predictability. These regular eruptions offer us a unique opportunity to study volcanic processes in detail, helping us understand not just Axial Seamount, but volcanoes in general.
Sarah Walker: so, what are the latest signs indicating that another eruption is imminent?
Dr. Emily carter: The data is quite compelling. We’ve been observing a steady increase in seismic activity, with hundreds of earthquakes occurring daily and a noticeable inflation of the seafloor. This expansion suggests magma is building up beneath the surface, putting immense pressure on the volcano’s structure.
Sarah Walker:
That sounds alarming! What kind of timeframe are we looking at?
Dr. Emily Carter:
Bill Chadwick, a leading geophysicist from Oregon State University, estimates the eruption is likely to occur between now and the end of 2025. However, predicting volcanic eruptions remains a complex challenge, and there are always factors we can’t predict with absolute certainty.
