Segment RO3 of the Northern East Pacific Rise lies between the Orozco and Rivera transform faults, immediately north of the Orozco transform. Unlike segment RO2 to the north, the RO3 segment displays a broad, shallow profile that is the widest and shallowest of a 5000-km-long segment of the East Pacific Rise between 23 degrees south to 23 degrees north. The flat axial crest ranges from 3-4 to about 10 km wide and is about 2300-2350 m deep; the axis morphology suggests a high magma supply rate. Magnetic paleointensity measurements on basaltic glasses dated several lava flows along segment RO3 at about 2000 +/- 1000 years, suggesting a major volcanic episode that produced lava flows flooding much of the axial plateau and extended on to its flanks. Several other lava flows were dated at "contemporary" ages, perhaps less than 100 years.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
