ASHES (Axial Seamount Hydrothermal Emissions Studies).
A seamount, submarine volcano, and underwater shield volcano in the Pacific Ocean, located on the Juan de Fuca Ridge. Standing 1,100 m (3,609 ft) high, Axial Seamount is the youngest volcano and current eruptive center of the Cobb–Eickelberg Seamount chain. Located at the center of both a geological hotspot and a mid-ocean ridge, the seamount is geologically complex, and its origins are still poorly understood. The volcano features an unusual rectangular caldera, and its flanks are pockmarked by fissures, vents, sheet flows, and pit craters up to 100 m (328 ft) deep. (Adapted from Wikipedia.)
Axial Seamount was first detected in the 1970s by satellite altimetry.
Eruptions were detected in 1998, 2011, 2025, and another one is expected in 2025.
