The Northwest Shepherd Islands group includes three volcanic cones on Emae Island (Pahunga, Talimasa, and Tipikal), Makura Island (~8 km SE of Emae), and the large submarine edifice under them. Williams and Warden (1964) report historical activity on Emae and some ashfall, which could have originated from a different volcano (Eissen et al. 1991). Warden (1967) reported strongly eroded summit craters and deep dissection of surficial deposits, and suggested that the Emae volcanoes may have become extinct in the Pliocene or early Pleistocene. Crawford et al. (1988) place Emae on the rim of a large caldera that extends to Mataso Island, more than 15 km S. Macfarlane et al. (1988) place two smaller uncertain calderas at this location; Eissen et al. (1991) did not find evidence for a caldera. Makura is largely composed of tilted lava flows.
