Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.Abstract Periodic high‐resolution imagery of Io is essential for understanding its surface evolution, from volcanic eruptions to tectonic deformation to large‐scale mass wasting. Juno flybys in 2023 and 2024 obtained imagery of the surface with the JunoCam imager at 1.8 km/pixel spatial resolution, comparable to global observations from the Galileo ...

Synchronized Eruptions on Io: Possible Evidence of Interconnected Subsurface Magma Reservoirs
Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.Abstract On 27 December 2024, Juno's JIRAM (Jovian InfraRed Auroral Mapper) instrument observed an unprecedented volcanic event in Io's southern hemisphere, covering a vast region of ∼65,000 km2, near 73°S, 140°E. Within the imaged region, only one hot spot was previously known (Pfd454).
