Most Recent Bulletin Report: December 1979 (SEAN 04:12)


Report of ash near the summit proves false

Most of the reported eruption sites were investigated during the 11-18 July cruise of the Fijian research vessel RV Bulikula. An inspection of Late Island, where whitish material thought to be ash reportedly covered the summit cone on 18 and 21 May, revealed no trace of a whitish covering other than scattered patches of white lichen, and no evidence of a recent eruption.

The small, 6-km-wide circular island of Late, lying along the Tofua volcanic arc about 55 km WSW of the island of Vavau, contains a 400-m-wide, 150-m-deep summit crater with an ephemeral lake. The largely submerged basaltic-andesite to andesitic volcano rises 1500 m from the sea floor, with its conical summit reaching 540 m above sea level. Cinder cones are found north of the summit crater, west and north of a semicircular plateau 100-150 m below the summit, and on the NW coast. A graben-like structure on the NE flank contains two large pit craters, the lower of which is partially filled by a saltwater lake. Only two eruptions have occurred in historical time, both from NE-flank craters, which produced explosive activity and possible lava flows in 1790 and 1854.

An aerial photo of Late taken July 1990 shows the main summit crater breached to the SE and a NE graben occupied by large pit craters, the largest of which contains a saltwater lake. Except for remnant of a small lava plug in the summit crater, no fresh lava flows are present. The small, 6-km-wide circular island of Late rises 1500 m from the sea floor, with its conical summit reaching 540 m above sea level.

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.
