Short summary
3-D seismic reflection data reveal that deepwater volcanoes have rugged basal contacts, which truncate underlying strata, and erupted lava flows that feed lobate lava fans. The lava flows (>  9 km long) account for 50–97 % of the total erupted volume. This indicates that deepwater volcanic edifices may thus form a minor component (~ 3–50 %) of the extrusive system and that accurate estimates of erupted volume require knowledge of the basal surface of genetically related lava flows.
