The Geography of Loki Basin
Loki Basin is one of the most prominent features on Io, characterized by its vast lava lakes and intense thermal activity. Spanning approximately 200 kilometers in diameter, it is home to Loki Patera, the largest volcanic depression on the moon. The basin’s unique geography is shaped by continuous volcanic eruptions, making it a hotspot for studying extraterrestrial volcanism. (Loki Patera, volcanic depressions, extraterrestrial volcanism)
Formation and Volcanic Activity
The formation of Loki Basin is closely tied to Io’s tidal heating, a result of Jupiter’s gravitational pull. This process generates immense heat, fueling the moon’s volcanic activity. Loki Patera, in particular, experiences periodic eruptions, with lava temperatures reaching up to 1,600°C. These eruptions reshape the basin’s surface, creating a constantly evolving landscape.
