Origin And Quantification Of Diffuse Co2 And H2s Emission At Crater Hills, Yellowstone National Park, Peipei Lin
Origin And Quantification Of Diffuse Co2 And H2s Emission At Crater Hills, Yellowstone National Park, Peipei Lin
Dissertations, Master's Theses and Master's Reports - Open
At Crater Hills, a thermally-altered area adjoining the Sour Creek resurgent dome that is located within the Yellowstone Caldera, we characterized volatile emissions based upon our soil degassing measurements and soil gas chemistry in 2014 and fumarole gas chemistry in 2007 (Bergfeld et al., 2011). The investigation at Crater Hills on its diffuse gases isotopes and CO2, H2S emission improve our understanding on its gas emission mode – including total emission and spatial distribution, and contribute to a more accurate estimation of total CO2 emission at Yellowstone volcanic system. The total emission of CO2 interpolated by sequential Gaussian simulation method …
Evaluation Of The Evolving Stress Field Of The Yellowstone Volcanic Plateau From 1988 To 2010 From Earthquake First Motions Inversion, Elena Russo
Dissertations, Master's Theses and Master's Reports - Open
Within the Yellowstone National Park, Wyoming, the silicic Yellowstone volcanic field is one of the most active volcanic systems all over the world. Although the last rhyolite eruption occurred around 70,000 years ago, Yellowstone is still believed to be volcanically active, due to high hydrothermal and seismic activity. The earthquake data used in this study cover the period of time between 1988 and 2010. Earthquake relocations and a set of 369 well-constrained, double-couple, focal mechanism solutions were computed. Events were grouped according to location and time to investigate trends in faulting. The majority of the events has oblique, normal-faulting solutions. …
