Submarine Volcanoes of the Solomon Islands Forearc Region

Solomon Islands submarine volcanoes in the New Georgia Group forearc are documented, including the frequently active Kavachi volcano and the elusive Cook volcano. The dataset compiles reported volcanic activity, bathymetric survey findings, and geological composition from sources like the Australian Ocean Data Network. Information was last updated in April 2026.

Use Cases

• Mapping volcano locations relative to subduction zones using reported coordinates and bathymetric profiles.
• Analyzing volcanic composition and activity patterns from described rock types (basalt-andesite, andesite-rhyolite) and eruption records.
• Assessing bathymetric survey gaps to plan future sonar mapping missions in the poorly surveyed forearc region.

Strengths

• Includes specific depth references, such as Kavachi rising 1000 m from the sea floor and Kana Keoki rising to within 700 m of sea level.
• Documents multiple named volcanic features (Kavachi, Cook, Kana Keoki) across the forearc region.

Limitations

• Sample size is small, describing only a few specific submarine volcanoes.
• Key data like precise coordinates, column names, and row counts are unavailable.
• Bathymetric coverage is described as 'very poorly surveyed', indicating incomplete spatial data.
