Volcanodle
Puzzle #5 was Kuril Arc at 46.3°N.
A shallow flat-topped edifice ~8 km in diameter, with depths from 0-50 m, is located in the Urup Strait ~15 km S of the Chernyye Brat'ya (Black Brothers) islands and ~20 km ENE of Urup Island in the Kuril Islands. Although visible using satellite bathymetry and appearing simply as a shallow platform on a map in Blokh et al. (2019) rather than a previously identified volcanic seamount, there is no available research about this edifice.

What the record says
Puzzle 5 ran on 14 Jul 2026 and the answer was Kuril Arc at 46.3°N, played with 6 guesses against 8 columns. On the record: Country - Russia; Region - Northwestern Pacific Volcanic Regions; Type - other; Tectonic setting - subduction; Elevation - submarine; Historically observed - not-observed. 2 of the 8 columns are blank in the source (Last eruption and Rock type), so nobody could score them either way.
Beyond the grid the record adds Largest recorded eruption - VEI 0; Holocene eruptions recorded - 2 eruptions.
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.
