09/1992 (BGVN 17:09) Thermal plumes detected over seamount crater
09/1992 (BGVN 17:09) Bathymetric survey reveals gas emission
A bathymetric survey in the vicinity of Kavachi volcano was carried out on 11 August by the HMNZS Tui. The ship made three parallel transits, ~1,200 m apart, over the summit of the unnamed seamount ~7 km NW of Kavachi. The summit is mostly flat, with a depth of at least 130 m found on each pass. The transit farthest NE showed a shallow and a deep crater on the tracing of the 12 kHz echo sounder. The 44-kHz echo sounder showed two small plumes rising to mid-water depth on either side of the smaller crater.

An E-W-trending chain of seamounts is located immediately north of Kavachi submarine volcano. The westernmost seamount, located 7 km NW of Kavachi, is the largest, and has a flat-topped summit that extended to within 70-m of the sea surface during a 1979 bathymetric survey. Its summit is covered with calcareous rocks and is fringed by a reef, but thermal plumes were detected in 1992 from one of its two summit craters. The central seamount to the east is lower and reaches to within 450 m of the sea surface. The summit of the easternmost seamount, 9-km NE of Kavachi, lies 240-m beneath the ocean surface. This unnamed andesitic seamount appears to have been formed by relatively recent eruptions.
The Global Volcanism Program is not aware of any Holocene eruptions from Unnamed. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Unnamed page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
The Global Volcanism Program has no synonyms or subfeatures listed for Unnamed.
The Global Volcanism Program has no photographs available for Unnamed.
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.
