The upward movement of the Yellowstone caldera floor between 2004 and 2008—almost 75 millimetres (3.0 in) each year—was more than three times greater than ever observed since such measurements began in 1923. [116] From 2004 to 2008, the land surface within the caldera moved upward as much as 8 inches (20 cm) at the White Lake GPS station.
The Valles Caldera Preservation Act of 2000 also created the Valles Caldera Trust, an experimental management organization consisting of nine board members, including seven appointed by the President of the United States. [10] The Trust combined private-sector practices with federal land management protocol.
Map of Long Valley Caldera Early winter in Long Valley, 2017. Long Valley Caldera is a depression in eastern California that is adjacent to Mammoth Mountain.The valley is one of the Earth's largest calderas, measuring about 20 mi (32 km) long (east-west), 11 mi (18 km) wide (north-south), and up to 3,000 ft (910 m) deep.
Caldera structure is similar on all of these planetary bodies, though the size varies considerably. The average caldera diameter on Venus is 68 km (42 mi). The average caldera diameter on Io is close to 40 km (25 mi), and the mode is 6 km (3.7 mi); Tvashtar Paterae is likely the largest caldera with a diameter of 290 km (180 mi). The average ...
The McDermitt Caldera is a large, oval-shaped caldera west of McDermitt in southeastern Oregon and northern Nevada in the United States. It is about 28 miles (45 km) long north–south and 22 miles (35 km) wide east–west. [3] The western part of the caldera is in the Trout Creek Mountains, and the northern part is in the Oregon Canyon Mountains.
This caldera had three main pulses of activity during its formation. [8] The second large eruption was about 1.3 Ma and created the Henrys Fork Caldera. [4] This eruption produced more than 280 km2 of magma [7] and was nested within a portion of a larger caldera, the Huckleberry Ridge Caldera. [4]
