Improving Reno Earthquake Hazard Assessment Through a Ground-Motion Model Analysis and Paleoseismic Study
… results of two complimentary methods to assess earthquake hazards around Reno, Nevada. First, we evaluate the performance of the four NGA-West2 (2014) Active Crustal models, which are trained on a global dataset of ground motion recordings, in the context of the Reno area. We compare the …

Neotectonic deformation features in plio-pleistocene coastal aeolianites: palaeoseismology and earthquake hazard implications for the Southern Cape, South Africa
… upper-crustal stress field, and infer seismic hazard. Previous studies indicate possible Quaternary faulting within the Southern Cape, major faults within the underlying geology, and a horizontal maximum compressive stress (SHmax) orientated WNWESE to NW-SE. This study utilised geological …

Probabilistic Assessment of Non-Ductile Reinforced Concrete Frames Susceptible to Mid-America Ground Motions
The infrequent nature of earthquakes in the Central and Eastern United States (CEUS), and the fact that none with intensity comparable to the New Madrid sequence of 1811 12 or the Charleston earthquake of 1886 has occurred in the past century, have caused the earthquake hazard in the region to be …

Performance-Based Analysis of Steel Buildings: Special Concentric Braced Frame
… Life Safety limit for the 2/3 maximum considered earthquake (MCE) hazard. This trend continued to the maximum considered earthquake hazard as well, under which the overall building performance for the linear procedures did not reach the Collapse Prevention level, which occurred in the nonlinear …

Estimation of Non-Linear Seismic Site Effects for Deep Deposits of the Mississippi Embayment
… the thesis describes the probabilistic seismic hazard analysis with non-linear site effect performed in the ME to develop site coefficients. Current site coefficients, proposed in National Earthquake Hazard Reduction Program (NEHRP), are used with USGS hazard maps to develop site specific …

Seismic attenuation of regional phases in the northern Middle East and the Tibetan Plateau
… other methods by eliminating the influence of earthquake source, instrument response, and site responses. I have measured regional phase Q values for two continental-continental collision zones, the northern Middle East and the Tibetan Plateau. The regional phase Q is typically assumed as the …

Column Capacity Evaluation For Low-Rise Moment Frame Steel Buildings In Mississippi Subject To Wind And Seismic Hazards
… a range of relative importance for these two hazards. For a three-story moment resisting frame building, second-order effects were developed for each column using the Amplified First Order Analysis Method. Interaction ratios were then used as the basis for establishing capacity of each column …

Station Delays, Their Standard Deviations, and Event Relocations in the Reno-Area Basin from a Dense USArray Flexible Array Deployment during the 2008 West Reno Earthquake Swarm
The seismic hazard of a sedimentary basin is high. The basin depth and its geometry control the amplification of ground motion. So from the point of earthquake hazard, it is important to know the basin geometry and its depth for the hazard evaluation of an area. Knowing the basin geometry and depth …

Present-day and late Quaternary crustal deformation along the southern Dead Sea Fault System, Jordan
Theoretical models of the earthquake cycle predict that crustal rheology may lead to differences between short-term crustal deformation rates (decadal time scales) and long-term fault slip rates (Holocene to late Pleistocene time scales). This study investigates fault kinematics along the southern …

Analysis of Seismicity and Related Seismic Risk in Muslim Countries: Case Studies from Afghanistan and Pakistan
<p>How communities respond to a natural hazard is influenced by how they perceive it. This dissertation evaluated the gap between intent and action regarding earthquake hazards in Muslim countries with a focus on Afghanistan and Pakistan. Cultural biases provided predictions of risk perceptions and …

Active tectonics and earthquake hazards in continental mountain ranges and foreland basins
… active mountain belts are exposed to significant earthquake hazard, since the range-bounding faults produce large earthquakes, and the underlying geological structure amplifies the resulting ground shaking. The aim of this dissertation is to investigate the regional-scale controls on earthquake …

Hybrid Steel Frames
… objectives (like life safety) under high earthquake hazard levels. However, the building performance at low performance objectives (like immediate occupancy) under low earthquake hazards is uncertain. The motivation of this research is to modify the design and detailing rules to make the …
