Lo Yellowstone è un vulcano situato negli Stati Uniti noto per aver prodotto in passato alcune tra le eruzioni vulcanichepiù forti di sempre. Photo by JT Rayon Unsplash. Per tale motivo e per via delle sue dimensioni e dell'enorme camera magmatica lo Yellowstone è considerato un supervulcano. INDICE.

Most of Earths history (from the formation of the earth 4.6 billion years ago to approximately 541 million years ago) is known as the Precambrian time. Rocks of this age are found in northern Yellowstone and in the hearts of the nearby Teton, Beartooth, Wind River, and Gros Ventre mountain ranges. During the Precambrian and the subsequent Paleozoic...
The rate of rise slowed in 2008 and the caldera began to subside again during the first half of 2010. The uplift is believed to be caused by the movement of deep hydrothermal fluids or molten rock into the shallow crustal magma system at a depth of about 10 km beneath the surface. A caldera may undergo episodes of uplift and subsidence for thousand...
The most likely activity would be lava flows, such as those that occurred after the last major eruption. A lava flow would ooze slowly over months and years, allowing plenty of time for park managers to evaluate the situation and protect people. No scientific evidence indicates such a lava flow will occur soon.
To monitor volcanic and seismic activity in the Yellowstone area the Yellowstone Volcano Observatory (YVO) was established in 2001. YVO is partnership of scientists from the US Geological Survey, National Park Service, University of Utah, University of Wyoming, University NAVSTAR Consortium (UNAVCO) and the state Geological Surveys of Wyoming, Mont...

Learn about the history and geology of the Yellowstone supervolcano, one of the world's most active and powerful volcanic systems. Explore how magma, hot spots, and calderas shaped the landscape and influenced the ecosystem of the park.
The Yellowstone Volcano Observatory (YVO) provides long-term monitoring of volcanic and earthquake activity in the Yellowstone National Park region. Yellowstone is the site of the largest and most diverse collection of natural thermal features in the world and the first National Park.
26 lug 2024 · Yellowstone Caldera, enormous crater in the western-central portion of Yellowstone National Park, northwestern Wyoming, that was formed by a cataclysmic volcanic eruption some 640,000 years ago. It measures approximately 30 by 45 miles (50 by 70 km), covering a large area of the park.
