Something Is Forcing Magma Into This Oregon Volcano — And It's Coming From 4,500 Miles Away

Three hundred miles off the Oregon coast, beneath nearly a mile of Pacific water, Axial Seamount is swelling beyond every eruption threshold scientists have recorded in the past three decades. For twenty years, this underwater volcano followed a pattern. It inflated. It erupted. It deflated. In 2015, researchers successfully predicted its eruption months in advance — a historic first in volcanology. Now the pattern has broken. The caldera has risen higher than it stood before any previous eruption. Seismic swarms are increasing. And a magnitude 8.8 earthquake 4,500 miles away in Kamchatka sent seismic waves directly through Axial’s magma system — triggering automated eruption alerts. Is this remote earthquake triggering? Is Axial being influenced by forces far beyond the Juan de Fuca Ridge? And what happens if the inflation does not stop? In this documentary, we examine: Real-time data from the Ocean Observatories Initiative Seafloor uplift measurements and bottom pressure records The 1998, 2011, and 2015 eruption cycles The Kamchatka megathrust earthquake and remote triggering theory The Blanco Fracture Zone’s potential stress transfer The tectonic connection between Axial and Cascadia The new sealed physics-based eruption forecasts Axial Seamount is the most instrumented submarine volcano on Earth. But even with 660 miles of fiber-optic cable and 140+ monitoring instruments, scientists admit the system is behaving in ways their models did not anticipate. The caldera is still rising. The instruments are still recording. And the next signal has not yet arrived. #oregon #seafloor #breakingnews
