Infrared image showing night-time thermal emission from the lava lake Pele. Galileo arrived at the Jupiter system in 1995 and, from 1996 to 2001, regularly monitored volcanic activity on Io through observations of Io's thermal emission at near-infrared wavelengths, imaging Io while it was in the Jupiter's shadow in order to look for thermal hotspots at visible and near-infrared wavelengths ...
The most powerful volcanic eruption observed on Io was an "outburst" eruption at Surt, observed by Earth-based astronomers on February 22, 2001. [ 51 ] Explosion-dominated eruptions occur when a body of magma (called a dike ) from deep within Io's partially molten mantle reaches the surface at a fissure.
The volcanic activity spotted on a planet famed for such eruptions was special for two reasons: Not only was the hot spot larger than Earth’s Lake Superior, but it also was seen belching out ...
Two Galileo images showing surface changes from a major eruption at Pillan Patera in 1997 Pillan Patera is a patera , or a complex crater with scalloped edges, on Jupiter 's moon Io . It is located at 12°20′S 243°15′W / 12.34°S 243.25°W / -12.34; -243.25 ( Pillan Patera ) , south of Pillan Mons and west of Reiden

A volcano near Iceland's capital Reykjavik in the country's southwestern region erupted for the tenth time in three years on Wednesday, local authorities reported.. The country's meteorological ...
The term has also become the generic term for referring to these structures. Small shield volcanoes use the term tholus or the plural tholi, e.g. Inachus Tholus. Finally, channels carved by volcanic lava flows through thermal erosion use the term vallis or the plural valles. See also the list of mountains on Io and the list of regions on Io.
