Volcanodle
Puzzle #83 was Kasuga 1.
Kasuga 1, the northernmost of three seamounts in the the Kasuga seamount chain SE of Fukujin, rises from a depth of 3,000 m to within about 600 m of the ocean surface. A series of flank vents are located low on the southern side of the edifice. The summit does not have a caldera or display hydrothermal activity, and is largely covered by volcaniclastics.

Volcanodle builds its record from Global Volcanism Program, Smithsonian Institution (Venzke, E. (ed.), Volcanoes of the World, volcano.si.edu). The description above comes from the same place the game credits on every reveal: A verbatim excerpt of the volcano's GVP Geological Summary. The puzzle itself is still playable in the archive, and every answer that has been and gone is listed on the past-answers page.
