The Yellowstone Caldera, sometimes referred to as the Yellowstone Supervolcano, is a volcanic caldera and supervolcano in Yellowstone National Park in the Western United States. The caldera and most of the park are located in the northwest corner of the state of Wyoming. The caldera measures 43 by 28 miles (70 by 45 kilometers), and postcaldera ...
The 1959 Hebgen Lake earthquake (also known as the 1959 Yellowstone earthquake) [4] occurred in the western United States on August 17 at 11:37 pm (MST) in southwestern Montana. [4][5] The earthquake measured 7.2 on the moment magnitude scale, [1] caused a huge landslide, resulted in over 28 fatalities and left $ 11 million (equivalent to $115 ...
44°26′N 110°40′W / 44.43°N 110.67°W / 44.43; -110.67. The Yellowstone hotspot is a volcanic hotspot in the United States responsible for large scale volcanism in Idaho, Montana, Nevada, Oregon, and Wyoming, formed as the North American tectonic plate moved over it. It formed the eastern Snake River Plain through a succession ...
Lava Creek Tuff. The Lava Creek Tuff is a voluminous sheet of ash-flow tuff located in Wyoming, Montana and Idaho, United States. It was created during the Lava Creek eruption around 630,000 years ago, which led to the formation of the Yellowstone Caldera. This eruption is considered the climactic event of Yellowstone's third volcanic cycle.
Updated November 29, 2023 at 7:45 PM. A series of “hidden” geological hazards has been uncovered in the northern reaches of Yellowstone National Park, including active faults that could pose ...
The caldera — a 50-mile-wide volcanic crater — is the remnant of a pair of massive volcanic eruptions thrown up by the Yellowstone hotspot as it wandered east to its current location. At its ...
Infrastructure damage at Hebgen Lake due to the 7.2 magnitude earthquake of 1959. Yellowstone experiences thousands of small earthquakes every year, virtually all of which are undetectable to people. About 2/3 of the earthquakes occur in an area between Hegben Lake and the Yellowstone Caldera along a buried fracture zone left from the 2.1 mya ...
The popular tourist spot is located roughly two miles northwest of Old Faithful. Volcanic activity for the Yellowstone region remains at normal levels, according to USGS.
