Approximately 300 miles off Oregon’s coast, scientists are closely monitoring Axial Seamount, an underwater volcano showing signs of imminent eruption. Recent activities include a surge in earthquakes—over 1,000 per day—and noticeable swelling of the volcano, indicating it’s filling with magma. Researchers, including Bill Chadwick from Oregon State University, suggest it could erupt soon, potentially before the year’s end.
Axial Seamount, located at the junction of the Pacific and Juan de Fuca tectonic plates, has erupted three times since 1998, with the last eruption occurring in 2015 when it released a significant volume of lava, about 450 feet thick. Despite its powerful activity, the volcano poses no direct threat to human safety, as it is submerged about a mile underwater. Even a large eruption would likely go unnoticed by nearby boats and have no impact on coastal communities.
Chadwick and colleagues are utilizing a network of sensors to study the volcano’s behavior, aiming to develop a better understanding of eruption patterns for more accurate forecasting. However, predicting volcanic eruptions remains challenging. While short-term forecasts are somewhat reliable, long-term predictions are still problematic due to the complex and unpredictable nature of volcanic behavior.
Axial Seamount serves as an effective research site for refining eruption forecasting techniques, given its remote location and the lack of serious risks to human life. This allows scientists to test models and improve prediction accuracy without the pressures that come with forecasting eruptions near populated areas. Overall, monitoring Axial Seamount not only enhances volcanic understanding but provides valuable insights into magma movement and eruption triggers.
