The CoAxial segment of the Juan de Fuca Ridge is about 435 km W of the Oregon coast, NE of Axial volcano. A submarine eruption along the CoAxial segment that produced thermal plumes and a new lava flow was detected by acoustic hydrophones in June 1993, just days after installation of the hydrophone system. This was the first deep-sea volcanic eruption detected as it was happening. The location of the eruption was at a depth of about 2,400 m, about 37 km NE of Axial volcano. Bathymetric surveys indicated that one or more additional sea-floor lava extrusions took place immediately east of the 1993 lava flow sometime between 1981-82 and 1991.
