Introduction

The CoAxial segment of the Juan de Fuca Ridge is located about 435 km west 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 marked the first deep-sea volcanic eruption that was detected as it was happening. The location of the eruption was at a depth of about 2400 m, about 37 km NE of Axial volcano. Bathymetric surveys indicated that one or more additional sea-floor lava extrusions took place immediately to the east of the 1993 lava flow sometime between 1981-82 and 1991.
