Details for: Axial Seamount
A eruption from the southern end of Axial caldera in 1998 produced a submarine lava flow with these distinctive collapse areas. Axial Seamount rises 700 m above the mean level of the central Juan de Fuca Ridge crest about 480 km west of Cannon Beach, Oregon to within about 1400 m of the sea surface. The 3 x 8 km Axial caldera is breached to the SE and is defined on three sides by boundary faults of up to 150 m relief. Hydrothermal vents colonized with biological communities are located near the caldera fault or along the rift zones. Photo courtesy of NOAA NeMo Observatory, 2006.
