How does the Yellowstone hotspot shape the landscape?

The Yellowstone hotspot is a volcanic feature beneath the North American tectonic plate responsible for large-scale volcanism and caldera-forming supereruptions across multiple states. As the tectonic plate moves over the stationary hotspot, it creates successive calderas, including the prominent Yellowstone Caldera. This ongoing magmatic activity fuels the park's extensive hydrothermal systems, geysers, and earthquakes.

What we know

• The Yellowstone hotspot is a volcanic hotspot underlying the North American tectonic plate, causing large-scale volcanism across Idaho, Montana, Nevada, Oregon, and Wyoming. [2]
• The movement of the North American tectonic plate over the hotspot formed the eastern Snake River Plain through a succession of caldera-forming eruptions. [2]
• The most recent caldera-forming supereruption of the Yellowstone hotspot, known as the Lava Creek Eruption, took place approximately 640,000 years ago. [2]
• The Yellowstone volcanic field remains active with continuing earthquakes, ground deformation, and extensive hydrothermal activity driven by an underlying magmatic system. [4]

Still open

• Geologists debate whether hotspots are caused by deep mantle plumes rising as thermal diapirs from the core-mantle boundary or by lithospheric extension permitting passive melt from shallow depths due to weak or thin crust.
