Geological Background

The islands of Nguna, Pele, and Emau, north of Vate Island (also known as Efaté), have been variously mapped as Pleistocene and Pleistocene to Holocene. Late-Pleistocene to Holocene eruptions constructed composite basaltic cones with well-preserved craters. Largely submarine calderas north of Vate Island of varying sizes have been inferred, ranging from a large caldera whose southern rim is defined by the islands of Nguna, Pele, and Emao to a smaller caldera, but their submarine morphology is difficult to define. Pumiceous deposits of the Efaté Pumice Formation cover much of Vate (Efaté) Island and record a major trachydacitic explosive eruption about 1 million years ago that originated from a submarine vent somewhere north of the island.

The Global Volcanism Program is not aware of any Holocene eruptions from North Vate. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the North Vate page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

The three small islands of Nguna, Pele, and Emau at the upper left, lie north of the large island of Efete (also known as Vate). Nguna and Pele appear to be a single island in this NASA Space Shuttle image (with north to the upper left), and Emau is the small circular island at the at the top center. These islands lie along or near the southern rim of a postulated largely submarine caldera of uncertain dimensions that extends to the north and may have formed about 2000 years ago.

Nguna Island, along with Pele and Emau Islands, lie north of Efate Island (also known as Vate). Largely submarine calderas of varying dimensions have been postulated in the North Vate area, and late-Pleistocene to Holocene eruptions have constructed composite basaltic cones with well-preserved craters.
