TimeMag. / DepthDistanceLocation
Lava flows from a very recent volcanic eruption were observed in 1994 along segment K of the southern East Pacific Rise.

Background:

This segment of the mid-ocean ridge north of the Easter microplate displays the broadest cross-sectional area and the shallowest depth (2566 m) of the southern East Pacific Rise between 13 degrees 40 minutes and 18 degrees 30 minutes south. Glassy, unsedimented lava flows on the 17.5 degrees S segment of the East Pacific Rise were considered from biological observations and chemical analyses of the plume and vent fluids to have been erupted within 2-3 years of a November-December 1993 plume survey. Lava was erupted along two segments of the mid-ocean ridge, a 4-km-long flow at the southern site and a 5-10 km long flow at the northern site. Numerous low- and high-temperature hydrothermal vents are active along this segment of the mid-ocean ridge.
