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 ...
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 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 ...
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 ...
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]
Steamboat Geyser, in Yellowstone National Park 's Norris Geyser Basin, is the world's tallest active geyser. Steamboat Geyser has two vents, northern and southern, approximately 20 feet (6.1 m) apart. The north vent is responsible for the tallest water columns; the south vent's water columns are shorter.

Jon F. Claerbout (born February 14, 1938) is an American geophysicist and seismologist. He is the Cecil Green Professor Emeritus of Geophysics at Stanford University. Since the later half of the 20th century, he has been a leading researcher and pioneered the use of computers in processing and filtering seismic exploration data, eventually ...
IRIS ( I ncorporated R esearch I nstitutions for S eismology [ 1]) was a university research consortium dedicated to exploring the Earth's interior through the collection and distribution of seismographic data. IRIS programs contributed to scholarly research, education, earthquake hazard mitigation, and the verification of a Comprehensive ...
