Complex styles of phreatomagmatic explosions at Kīlauea Volcano, Hawaii, controlled by magma structure
Jo Schmith, Donald A. Swanson
2023, Frontiers in Earth Science - Volcanology (11)
Explosive eruptions at basaltic volcanoes remain poorly understood. Kīlauea Volcano is a type locality for basaltic eruptions and is well-known for effusive activity. However, more than 7 m of phreatomagmatic Keanakākoʻi Tephra unit D deposits from explosive eruptions crown the southern rim of the summit caldera and provide...

Investigating microbial size classes associated with the transmission of stony coral tissue loss disease (SCTLD)
James S. Evans, Valerie J. Paul, Blake Ushijima, Kelly A. Pitts, Christina A. Kellogg
2023, PeerJ (11)
Effective treatment and prevention of any disease necessitates knowledge of the causative agent, yet the causative agents of most coral diseases remain unknown, in part due to the difficulty of distinguishing the pathogenic microbe(s) among the complex microbial backdrop of coral hosts. Stony coral tissue loss disease (SCTLD) is a...
Fluid migration pathways to groundwater in mature oil fields: Exploring the roles of water injection/production and oil-well integrity in California, USA
Peter B. McMahon, Matthew K. Landon, Michael J. Stephens, Kimberly A. Taylor, Janice M. Gillespie, Tracy Davis, David H. Shimabukuro
2023, Science of the Total Environment (900)
Mature oil fields potentially contain multiple fluid migration pathways toward protected groundwater (total dissolved solids, TDS, in nonexempted aquifer <10,000 mg/L) because of their extensive development histories. Time-series data for water use, fluid pressures, oil-well construction, and geochemistry from the South Belridge and Lost Hills mature oil...

A Monte-Carlo chemical budget approach to assess ambient groundwater flow in bedrock open boreholes
Philip Harte
2023, Groundwater Monitoring and Remediation (44) 57-71
In low-permeability rocks, ambient groundwater flow in open boreholes may go undetected using conventional borehole-flowmeter tools and alternative approaches may be needed to identify flow. Understanding ambient flow in open boreholes is important for tracking of cross contamination in groundwater. Chlorinated volatile organic compound (CVOC)...

Browsers or Grazers? New insights into feral burro diet using a non-invasive sampling and plant DNA metabarcoding approach
Saeideh Esmaeili, Kathryn A. Schoenecker, Sarah King
2023, Animals (13)
By selecting certain plants for consumption, ungulates (hoofed mammals) shape ecosystems and influence which plant species are present in their habitats. We investigated the summer diets of non-native feral burros in two ecosystems: a subtropical Sonoran Desert in Arizona and a temperate juniper shrubland in Utah, the United States....

The spatial distribution of debris flows in relation to observed rainfall anomalies: Insights from the Dolan Fire, California
David B. Cavagnaro, Scott W. McCoy, Matthew A. Thomas, Jaime Kostelnik, Donald N. Lindsay
2023, Conference Paper
A range of hydrologic responses can be observed in steep, recently burned terrain, which makes predicting the spatial distribution of large debris flows challenging. Studies from rainfall-induced landslides in unburned areas show evidence of hydroclimatic tuning of landslide triggering, such that the spatial distribution of events is best predicted by...
Bedrock erosion by debris flows at Chalk Cliffs, Colorado, USA: Implications for bedrock channel evolution
Francis K. Rengers, Jason W. Kean, Jeffrey A. Coe, Megan Hanson, Joel Smith
2023, Conference Paper
Debris flow erosion into bedrock helps to set the pace of mountain denudation, but there are few empirical observations of this process. We studied the effects of debris flows on bedrock erosion using Structure-From-Motion photogrammetry and multiple real-time monitoring measurements. We found that the distribution of bedrock erosion across the...
Ground‐motion variability from kinematic rupture models and the implications for nonergodic probabilistic seismic hazard analysis
Grace Alexandra Parker, Morgan P. Moschetti, Eric M. Thompson
2023, Seismological Research Letters (94) 2687-2697
The variability of earthquake ground motions has a strong control on probabilistic seismic hazard analysis (PSHA), particularly for the low frequencies of exceedance used for critical facilities. We use a crossed mixed‐effects model to partition the variance components from simulated ground motions of M<mi...
Using integrated growth to delineate debris-flow inundation
Mark E. Reid, Dianne L. Brien, Collin Cronkite-Ratcliff, Jonathan P. Perkins
2023, Conference Paper
Debris-flow volume is fundamental to mobility, yet many debris flows change volume as they travel. Growth can occur through diverse processes such as channel-bed entrainment, bank failures, aggregation of landslides, and coalescence of multiple flows. Integrating growth, either over upslope area or stream length, combines the effects of these growth...
