Low-frequency Teleseismic and Infrasound Arrivals along the Dense Corvallis Nodal Array

Creator:: Way, Rachel
Abstract:: The dense Corvallis array deployed in January of 2022 aided in the high-resolution study of local geology. This array was made of 177 SmartSolo 3-component 5 Hz geophones around Corvallis, with a 93 geophone profile going west towards Bald Hill for approximately 5 km at an average of 64 m...

Lidar-based Post-earthquake Pavement Damage Classification System

Creator:: Shakya, Suzanna
Abstract:: 3D laser scanning has been used extensively in engineering reconnaissance surveys to capture perishable data in an efficient, reliable, and precise manner. Many insights on damage can be obtained from the data through various methods of post-processing; however, many of these techniques are often labor intensive. This delay reduces the...

Olivine and plagioclase-hosted melt inclusions and their application to determining parental arc magmas

Creator:: Kohut, Edward John
Abstract:: Three broadly interrelated problems of critical significance to the proper interpretation of melt inclusion (MI) data are addressed in this thesis. The first issue, the petrogenesis of anorthitic plagioclase phenocrysts in MORB lavas, has relevance due to the presence of numerous MI in many high-An feldspars. This problem was addressed...

Seismotectonics of the Himalayas and the Tibetan Plateau : moment tensoranalysis of regional seismograms

Creator:: Baur, Jan R.
Abstract:: This thesis presents a detailed seismotectonic investigation of the Himalayan region and the Tibetan plateau as part of project HiCLIMB to explore the state of stress and the kinematics of the world’s largest continental collision zone. Using full regional waveforms for moment tensor inversion, source parameters for 107 earthquakes were...

The timing and evolution of Cenozoic extensional normal faulting in the southern Tobin Range, Pershing County, Nevada

Creator:: Gonsior, Zachary J.
Abstract:: The Tobin Range of central Nevada lies in the Basin and Range extensional province near the transition between more extended terrane (>50%) to the south and east, and generally less extended terrane to the north and west. Geologic mapping, 40Ar/39Ar dating and whole-rock geochemical analysis were employed to establish the...

Degree and scale of interactions among chiefdoms during the pre-Hispanic late period in northern Highland Ecuador (AD 1250-1525)

Creator:: Yanchar, Kaitlin C.
Abstract:: During the Late Pre-Hispanic period, settlements in Northern Highland Ecuador were organized under a number of chiefdoms. While a basic hierarchical political system is described in the ethnohistoric literature, the nature of the interactions between specific settlements has remained unknown. This study utilizes two methods for describing the degree and...

Spatial and Temporal Landscape Responses to Progressive Tectonic Forcing along California Fault Systems

Creator:: Manopkawee, Pichawut
Abstract:: Understanding the degree to which topography of erosional landscapes in active mountain belts encode the rates and patterns of active deformation in the upper crust is a primary goal in the field of tectonic geomorphology. In particular, the convolved influence of variations in rock mass quality and the erodibility of...

Late Holocene Earthquake History Recorded in Alluvial Fan Sequences, Panamint Valley, Eastern California

Creator:: Sethanant, Israporn
Abstract:: The Panamint Valley fault zone (PVFZ) is an active, dextral-oblique normal fault that partially accommodates dextral shear across the Eastern California Shear Zone (ECSZ). The fault system has a complex geometry, characterized by a relatively high-angle dextral oblique normal fault in the south and a low-angle detachment system that accommodates...

Creating a Predictive Model of Cinder Cone Evolution in Central Oregon

Creator:: Das-Toke, Shyam P.
Abstract:: Cinder cones are useful geomorphic features for geological analysis because they generally have known initial states and follow a similar pattern of degradation as they are exposed to erosive processes. This is largely because cinder cones are produced by monogenetic eruptions. Characterizing large cinder cone fields in terms of age...

Geomorphic Evidence for Differential Rock Uplift Across the Southern Cascadia Forearc

Creator:: von Dassow, Wesley
Abstract:: The nature of upper plate deformation along the Cascadia subduction zone (CSZ) is poorly understood. Systematic covariation among topographic relief, geodetically determined uplift rates, decadal to millennial erosion rates, and the frequency of episodic tremor and slip (ETS) along the Cascadia forearc suggest a genetic association between forearc topography and...
