Evaluation Of Geohazards In The Cape Girardeau Area Using Lidar And Gis, Southeast Missouri, Usa, Olufeyisayo B. Ososami, J. David Rogers, Francisca Oboh-Ikuenobe

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

The New Madrid Seismic Zone (NMSZ) has historically recorded some of the largest intensity earthquakes in North America, including significant earth movements that resulted in about 2000 felt earthquakes during 1811-1812. The region continues to experience mass wasting due to earth movements. The aim of this study is to understand the influence of geologic variables on mass wasting processes in the greater Cape Girardeau area, which forms the commercial center of Missouri's fertile "Bootheel" region. Earth movement susceptibility was evaluated in Cape Girardeau and Bollinger counties and portions of Stoddard and Scott counties by mapping potential landslide features on topographic …

Palynology And Paleoclimatology Of The Chicxulub Impact Crater In The Early Paleogene, Vann Smith

LSU Doctoral Dissertations

At the end of the Cretaceous Period, a large bolide impacted the Earth and formed the Chicxulub impact crater in the Yucatán Peninsula, Mexico. In 2016, International Ocean Discovery Program (IODP) Expedition 364 Site M0077 drilled into the buried peak ring of the crater, recovering a marine Paleocene to early Eocene post-impact section deposited on top of the impact breccia. Palynological analysis of 195 samples from the post-impact section has yielded the first pre-Holocene vegetational record from inside the Chicxulub impact crater and the first palynological record of the recovery of life following the end-Cretaceous mass extinction from inside the …

A Paleoseismic Study Of The Twin Lakes Fault, Mount Hood Fault Zone, Oregon, Charlie Carr, Ashley R. Streig

McNair Symposium

Recent geologic mapping on high-resolution topography from lidar has led to the discovery of a zone of active faults on Mount Hood. The Mt. Hood Fault Zone consists of four separate faults, and stretches ~55 km from south to north, and crosses the summit of Mount Hood. The focus of this study is the northern section of Twin Lakes Fault, which lies directly south of Mount Hood and adjacent to OR35 and the White River. Lidar topography reveals the west side down normal displacement on the Twin Lakes fault. The highest tectonic seismicity rates in the Mount Hood area occur …

Spatiotemporal Trends And Variability In The Centroid Of The Northern Hemisphere's Circumpolar Vortex, Nazla Bushra, Robert V. Rohli

Faculty Publications

Recent previous research has established the "sharpest gradient" approach to defining the circumpolar vortex and has identified correlations of the area and circularity of the Northern Hemisphere's circumpolar vortex (NHCPV) to important atmospheric-oceanic teleconnections. However, because geographical shifts in the NHCPV, independent of area or circularity changes, could affect surface environmental conditions, this research addresses the question of the extent to which the NHCPV centroid undergoes such shifts, both intra- and inter-annually. Results show that during the 1979-2017 period, the centroid has moved less on a daily basis in more recent years, perhaps indicative of a stabilization in circulation, with …

Analysis Of Gravity For The Crustal Structure Of Nepal Himalaya, Kapil Prasad Phuyal

Graduate Theses/Dissertations

Nepal Himalaya is situated in the central portion of the seismically active Himalayan Orogenic Belt, which is geologically segmented by four major mega fault structures: Main Frontal Thrust (MFT), Main Boundary Thrust (MBT), Main Central Thrust (MCT), and the South Tibetan Detachment System (STDS). The MFT, MBT, and MCT are part of the basal decollement Main Himalayan Thrust (MHT) which accommodates the convergence between the Indian and Eurasian Plate. The 2015 Gorkha Earthquake occurred within the MHT system, MHT system itself had been seismically locked since the 1934 Nepal-Bihar Earthquake, complicating the geometry depth of MHT. Available land and airborne …

Impact Of Calcium Carbonate Reactant Size And Mineralogy On Dolomite Stoichiometry, Katharine G. Rose

Masters Theses

Dolomite is a common, diagenetic, Mg-Ca carbonate mineral. Dolomitization occurs by a dissolution-precipitation reaction between a CaCO₃ precursor (calcite or aragonite) and Mg bearing fluids. The amount of Mg in dolomite, referred to as dolomite stoichiometry (mol% MgCO₃), varies in natural dolomites (38-50 mol% MgCO₃). Laboratory experiments have shown that dolomite stoichiometry is dependent on physiochemical factors of the diagenetic fluids (i.e., temperature, salinity, and Mg/Ca). The impact of the CaCO₃ precursor on stoichiometry, however, has not been studied directly. This study tests how the CaCO₃ precursor size (sieve size) and mineralogy (calcite …

Assessing The Prevalance Of Joint-Controlled Mass Wasting In The Southern Appalachian Mountains, U.S.A., Madeline Konopinski

Graduate Theses/Dissertations

Landslides are common hazards that produce devastating effects worldwide. Within the United States, the Appalachian Mountains are identified as an area of moderate to high susceptibility and incidence for landslides (Mirus et al., 2020; Wieczorek and Morgan, 2008). Given the presence of active seismic zones (eastern Tennessee and Giles County seismic zones) and variable rainfall due to seasonal storms (hurricanes) throughout the Appalachians, ancient earthquake activity or intense rainfall may trigger mass wasting events. Regional bedrock joints may further control the susceptibility of landslides to develop in specific locations during trigger events by providing a pre-existing weakness in the substrate. …

Geology Of The Clairmont Springs 7.5-Minute Quadrangle And Geochronology Of The Alabama Blue Ridge, Adelie Ionescu

Graduate Theses/Dissertations

The Alabama Blue Ridge (USA) of the southern Appalachians contains metamorphic rocks and structures associated with island arc accretion and continent-continent collision that record the Acadian and Alleghenian orogenies. The western Blue Ridge is underlain by Cambrian to Mississippian, clastic and carbonate, low-grade, greenschist facies metamorphic Talladega belt that formed outboard from the Alabama promontory or along the Laurentian margin. The eastern Blue Ridge contains the Neoproterozoic to Paleozoic, lithologically diverse, high grade, middle to upper amphibolite facies Ashland Supergroup. Geologic mapping of the Clairmont Springs 7.5- minute quadrangle unveils tectonic relationships between the eastern and western Blue Ridge and …

Understanding Potential Climate Change Impacts On Water Resources Within A Fractured Rock Watershed In Northern Togo, Mahawa-Essa Mabossani Akara

Dissertations

More than 72% of sub-Saharan Africa land surface is comprised of hard rock with fractured rock aquifers supplying water to an estimated 25% of the rural population. Given low porosity and storativity, fractured rock aquifers are particularly vulnerable to stresses such as projected population growth and climate variability. General circulation models of sub-Saharan Africa predict increases in temperature and in occurrences of extreme precipitation trends, such as flooding and drought. Adaptation strategies that promote optimal uses of water resources have emerged, although, most focus exclusively on surface water resources. This project investigates the potential impact of climate change on surface …

Multi-Proxy Approach To Robustly Capture Earthquake Temperature Rise At The Punchbowl Fault, California, Emma M. Armstrong

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Earthquakes produce heat along a fault surface from friction created as two blocks of rock move past each other. The amount of heat generated depends on a variety of factors, including rock type, stresses, and thickness of the fault zone. Identifying evidence for and quantifying this earthquake (coseismic) temperature rise are essential for identifying past earthquakes in the rock record. Indirect methods, such as textures and geochemical signatures that change with temperature, can serve as paleothermometers. Here we compare two paleothermometers, biomarkers and thermochronometry, from two transects across the Punchbowl fault (PF), California. The PF is an ancient fault strand …

Translating Risk Information To Protective Action: Examining Household Response To Information About Earthquake Hazards And Risk, Carson C. Macpherson-Krutsky

Boise State University Theses and Dissertations

Natural hazards have been a part of the landscape since its existence, but they are becoming more devastating as they intersect with growing populations and as climate change increases their frequency and intensity. As these changes occur, the need to understand how to reduce disaster impacts becomes paramount. Despite growing concern and increasing costs of disasters over the past decade, household preparedness, which is at the foundation of disaster readiness, has seen little to no improvement. Using two research experiments, we adopt the Protective Action Decision Model (PADM; Lindell & Perry, 2004; 2012) as a framework to investigate what motivates …

An Integrative Approach For Environmental Assessment And Water Resources Management Using Direct Current Resistivity (Dc), Geographic Information System (Gis), Remote Sensing, And Gain And Loss Method, Dina Ragab Desouki Abdelmoneim

Boise State University Theses and Dissertations

Sustainable water resource management is a crucial national and global issue (Currell et al., 2012). In arid areas, groundwater is often the major source of water or at least a crucial supplement to other freshwater resources for agriculture, industry and domestic consumption (Vrba and Renaud, 2016). The complexity associated with groundwater-surface water interactions creates uncertainty about water resource sustainability in semi-arid environments, especially with urbanization and population growth. Flood irrigation in the early 1900s increased the shallow groundwater table in the Treasure Valley (TV), but with increasing irrigation efficiencies, they have been declining since the 1960s with a mean decline …

Mafic Explosive Volcanism At Llaima Volcano: 3d X-Ray Microtomography Reconstruction Of Pyroclasts To Constrain Shallow Conduit Processes, Pedro Antonio Valdivia-Munoz

Boise State University Theses and Dissertations

Mafic eruptions, which are typically effusive to mildly explosive, can produce much stronger explosive eruptions. Eruption style is determined by the ability of gas to escape through the permeable network. If the permeability is sufficiently high to reduce vesicle overpressure during ascent, the volatiles may escape from the magma, inhibiting violent explosive activity. In contrast, if the permeability is sufficiently low to retain the gas phase within the magma during ascent, bubble overpressure may drive magma fragmentation. Rapid ascent rates may induce disequilibrium crystallization, increasing viscosity and explosivity, and have consequences for the geometry of the vesicle network. Quantitative vesicle …
