Article
Full-text available
A simple relation between pore pressure change and 1D surface deformation is presented. The relation is for pore pressure change in a confined aquifer that causes surface deformation. It can be applied to groundwater models of any discretization and is computationally efficient. The estimated surface deformation from model results can be compared t...
Article
Full-text available
Causal mechanisms for fluid injection-induced earthquakes remain a challenge to identify. Past studies largely established spatiotemporal correlations. Here, we propose a multi-process causal mechanism for injection-induced earthquakes through a case study of the 2017 Mw 5.5 induced earthquake near Pohang Enhanced Geothermal System, Korea, where de...
Article
People with disabilities are chronically underrepresented in many geoscience departments across the country. There are a number of proposed reasons why this underrepresentation persists, one of which is lack of instructor training in designing accessible curriculum and making high-quality accommodations. This not only puts students with accessibili...
Article
Full-text available
A simplistic triggering mechanism, pore pressure increase from injection, has been the focus of injection-induced seismicity studies for decades. Research into other possible mechanisms, like poroelastic stress changes, is ongoing, but there has been relatively little focus on earthquake interaction. While studies have looked at how moderate-magnit...
Conference Paper

The Hydrology Section Student Subcommittee, H3S, is dedicated to a number of ideas and issues within the geosciences complementary to those highlighted by the larger Hydrology Section. We strive to provide student members with opportunities for professional development as well as social interaction and networking within the broader geosciences comm...
Article
Full-text available
Mitigation of injection-induced seismicity in Greeley, Colorado, is based largely on proximity of wastewater disposal wells to seismicity and consists of cementation of the bottom of wells to eliminate connection between the disposal interval and crystalline basement. Brief injection rate reductions followed felt events, but injection rates returne...
Article
Full-text available
Utah is one of the top producers of oil and natural gas in the United States. Over the past 18 years, more than 4.2 billion gallons of wastewater from the petroleum industry has been injected into the Navajo Sandstone, Kayenta Formation, and Wingate Sandstone in Carbon and Emery Counties, central Utah, where seismicity has increased during the same...
Conference Paper
Full-text available
The objective of this study is to assess future changes in groundwater resources through the analysis of historical groundwater level data. Boulder County in Colorado is the study site that encompasses mountainous regions to the west and lowland plains to the east. We assess permitted wells in Boulder County constructed from 1950 to 2016. All well...
Article
Full-text available
The NEAR mission to 433 Eros provided detailed data on the geology, mineralogy, and chemistry of this S-class asteroid [McCoy, T.J., Robinson, M.S., Nittler, L.R., Burbine, T.H., 2002. Chem. Erde 62, 89–121; Cheng, A.F., 1997. Space Sci. Rev. 82, 3–29] with a key science goal of understanding the relationship between asteroids and meteorites [Cheng...

Full-text available
Metal-sulfide particles with included silicates in the dark portions of ordinary chondrite regolith breccias are possible asteroidal agglutinates formed by micrometeorite bombardment.
Article
Full-text available
The surface major element composition of the near-earth asteroid 433-Eros has been determined by x-ray fluorescence spectroscopy (XRS) on the NEAR-Shoemaker spacecraft [1]. The abundances of Mg, Al, Si, Ca and Fe match those of ordinary chondrites [1]. However, the observation that Eros appears to have a sulfur abundance at least a factor of two lo...
