This group of small islands (Ewose, Buninga, and Tongariki) SE of Tongoa Island have no obvious volcanic features. Although it has been suggested that they lie on the rim of a caldera (Crawford et al. 1988, Macfarlane et al. 1988), no evidence for such a feature was found by Eissen et al. (1991). Buninga and Tongariki appear to be the exposed parts of a submarine edifice that extends towards Emae island, 15 km SW. Pyroclastic rocks intruded by dikes are exposed on Ewose, whereas Buninga is largely composed of tilted lava flows. Tongariki consists of basalts with dacitic pumiceous tuffs in low-lying areas.
