A series of quakes has been detected at the Axial Seamount, an active submarine volcano located 250 miles off the Oregon coast and one mile beneath the Pacific Ocean. Considered the most active underwater volcano in the region, Axial sits directly along the Cascadia Subduction Zone — making it one of the most closely watched sites in the Pacific Northwest.

Thanks to the Ocean Observatories Initiative, new high-definition video streams from the seafloor are giving us a rare real-time look at hydrothermal vents and volcanic activity. These feeds capture the environment as pressure builds and changes unfold deep beneath the ocean.

While Axial has erupted three times in the past 25 years, its ongoing unrest reminds scientists that Cascadia’s volcanic and tectonic systems remain dynamic — and potentially dangerous.

In this video, we explore the latest activity at Axial Seamount, what the live video streams reveal, and why this hidden volcano is so important to the Cascadia region.
