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.

Macdonald K C, Haymon R, Shor A, 1989. A 220 km2 recently erupted lava field on the East Pacific Rise near lat 8° S. Geology, 17: 212-216.

A massive 15 +/- 4 cu km lava flow field covers about 220 sq km of the East Pacific Rise (EPR) axis crest at about 8 degrees South. The high reflectivity of the lava flow indicates a very youthful age. This, coupled with teleseismically recorded earthquakes in 1964, 1965, and 1969 of an unusual magnitude along this segment of the EPR and the detection of a helium megaplume of a volume consistent with the eruption of a lava flow of this volume detected several years later at a distant location consistent with inferred circulation patterns at mid-ocean depths led Macdonald et al. (1989) to suggest that part or all of this lava field may have been emplaced in the past 25 years, during one or more eruptions coincident with the earthquakes and onset of the helium plume.
