Axial Seamount is the most magmatically robust volcano on the Juan de Fuca Ridge spreading center, having erupted in 1998 and most recently in April 2015. It hosts numerous active hydrothermal fields and abundant sites of diffuse flow, and is expected to erupt again within the next 8 to 10 years. The Axial Caldera study site hosts myriad geophysical, chemical and biological instruments connected in real-time to the Internet via an array of junction boxes and extension cables, including an HD video camera trained on an active hydrothermal venting system.
