The first sentence of this Wikipedia article currently defines a subaqueous volcano as follows: "A subaqueous volcano is a volcano formed beneath freshwater and never builds above lake level.". The cited source (Haller and Hoffman "Geological Field Trips in Southern Idaho, Eastern Oregon, and Northern Nevada") used to support this claim states: "Subaqueous volcanoes erupt under water and never build above the lake level. Finally, subaerial volcanoes erupt through a buried aquifer system and produce classic maar volcanic features. All of these volcanic systems contain a significant amount of water, causing a high magma/water interaction. Emergent and subaqueous volcanoes usually form gently sloping tuff cones, whereas subaerial volcanoes form maars or tuff rings (Godchaux and others, 1992)." The scope of the cited source applies only to some volcanoes of the western part of the Snake River Plain in Idaho, not to all subaqueous volcanoes. The Wikipedia editor who added this definition to this article seems to have misunderstood the cited source and assumed that it applies globally. Subaqueous volcanoes are not restricted to lakes (as is already inconsistently shown elsewhere in this Wikipedia article which already (correctly) states "Subaqueous volcanoes are most commonly formed in oceans, but can also form in lakes, rivers and subglacial lakes."). "Subaqueous volcano" is a synonym of "submarine volcano". GeoWriter (talk) 20:00, 27 December 2020 (UTC)Reply
The lead section has been substantially revised since December 2020 and these changes fix the earlier contradictions and misconceptions. Therefore, I have removed the "This article appears to contradict itself on environment of formation. (December 2020)" text from the ""Multiple issues" template at the top of this article.
