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 ...
Hike / auto / bus. 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 ...
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.
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 ...
For the Yellowstone hotspot, seismological evidence began to converge from 2011 in support of the plume model, as concluded by James et al., "we favor a lower mantle plume as the origin for the Yellowstone hotspot." [88] [89] Data acquired through Earthscope, a program collecting high-resolution seismic data throughout the contiguous United ...
In May, after scientists found a crater a few feet (1-2 meters) wide in the Norris Geyser Basin 18 miles (29 kilometers) north of Biscuit Basin, they consulted acoustic and seismic data from the ...
The World-Wide Standardized Seismograph Network (WWSSN) – originally the World-Wide Network of Seismograph Stations (WWNSS) [1] – was a global network of about 120 seismograph stations built in the 1960s that generated an unprecedented collection of high quality seismic data. [2] This data enabled seismology to become a quantitative science ...
Seismic tomography. Seismic tomography or seismotomography is a technique for imaging the subsurface of the Earth with seismic waves produced by earthquakes or explosions. P-, S-, and surface waves can be used for tomographic models of different resolutions based on seismic wavelength, wave source distance, and the seismograph array coverage. [1]
