It was Yellowstone's third and most recent caldera-forming eruption. Geologists closely monitor the elevation of the Yellowstone Plateau, which has been rising as quickly as 150 millimetres (5.9 in) per year, as an indirect measurement of changes in magma chamber pressure. [41] [42] [43]
This in turn released the enclosed magma as lava and caused the surface above the emptied magma chamber to collapse. [20] Water later filled the collapsed area of the caldera, forming an extension of Yellowstone Lake. This created the source of heat and water that feed the West Thumb Geyser Basin today.

The magma chamber that lies under Yellowstone is estimated to be a single connected chamber, about 37 miles (60 km) long, 18 miles (29 km) wide, and 3 to 7 miles (4.8 to 11.3 km) deep. [85] The current caldera was created by a cataclysmic eruption that occurred 640,000 years ago, which released more than 240 cu mi (1,000 km 3 ) of ash, rock and ...

The zircon and phenocrysts rims recorded that the magma of the Lava Creek Tuff was generated from a mix of mantle, Archean crust, and shallow hydrothermally altered intra-caldera rocks. Member A and B were sourced from separate magma reservoirs prior to eruption, [ 19 ] at a depth range of 3–6 km (1.9–3.7 mi) [ 20 ] and a temperature of 790 ...

If magma continues to be injected into the collapsed magma chamber, the center of the caldera may be uplifted in the form of a resurgent dome such as is seen at the Valles Caldera, Lake Toba, the San Juan volcanic field, [7] Cerro Galán, [26] Yellowstone, [27] and many other calderas. [7]
