Axial Seamount is an active submarine volcano located ~300 miles offshore Oregon and about a mile below the ocean surface. It has erupted 3 times in the last 30 years, making it the most active volcano in the Pacific Northwest (even though you can't see it!). It is monitored in real-time by seafloor instruments connected to a cabled observatory. Data from that monitoring network suggest that the volcano is building toward its next eruption. This talk will describe the most recent monitoring data and its implications for forecasting the next eruption.
