Carlut J, Cormier M-H, Kent D V, Donnelly K E, Langmuir C H, 2004. Timing of volcanism along the northern East Pacific Rise based on paleointensity experiments on basaltic glass. J Geophys Res, 109: B04104, doi:10.1029/2003KB002672.

Segment RO2 of the Northern East Pacific Rise lies between the Orozco and Rivera transform faults, immediately south of the Rivera transform. The segment displays a typical small rifted axial crest, about 2-3 km wide and about 20-50 m deep. At some locations the summit trough almost disappears, suggesting high rates of volcanism. A seamount lies just east of the axial crest at about 16 deg 33 min N. Magnetic paleointensity measurements on basaltic glasses dated a lava flow at about 2000 +/- 1000 years and another at "contemporary" age, perhaps decades to a few hundred years old.
