Vertical Deformation Along The San Andreas Fault, Garrett Thornton Jan 2012

Vertical Deformation Along The San Andreas Fault, Garrett Thornton

Open Access Theses & Dissertations

There have been numerous M 6+ earthquakes along the San Andreas Fault System (SAFS) (Schwartz et al., 1984) (Figure. 1.1) in the historical past. These rupture events have created millions of dollars worth of damage, and have been responsible for multiple lives lost. An improved understanding of the motions and crustal characteristics along the SAFS can lead to better hazard mitigation (Bakun et al., 2005). Horizontal crustal motions of the SAFS have been widely studied and applied to seismic hazard models (WGCEP, 2007), however vertical motions are not often utilized due to their complicated origin and sometimes large uncertainties. This …


The Geography Of Greenhouse Gas Emissions From Within Urban Areas Of Asia, Jochen Albrecht, Peter Marcotullio, Andrea Sarzynski, Niels Schulz Jan 2012

The Geography Of Greenhouse Gas Emissions From Within Urban Areas Of Asia, Jochen Albrecht, Peter Marcotullio, Andrea Sarzynski, Niels Schulz

Publications and Research

This paper aims to advance two objectives: (1) identify and explore greenhouse gas emissions from urban areas in Asia at the regional level; and (2) explore covariates of urban greenhouse gas emissions. We use the Emissions Database for Global Atmospheric Research estimates for carbon dioxide, methane, nitrous oxide, and sulfur hexafluoride from 14 source activities for the year 2000, which are allocated on a 1/108 global grid. We extract emissions for 3535 urban extents all with populations over 50,000, accounting for approximately 91% of the region’s urban population. We use regression analysis to associate emissions with urban area and growth, …


Mapping And Assessing Urban Impervious Areas Using Multiple Endmember Spectral Mixture Analysis: A Case Study In The City Of Tampa, Florida, Fenqing Weng Jan 2012

Mapping And Assessing Urban Impervious Areas Using Multiple Endmember Spectral Mixture Analysis: A Case Study In The City Of Tampa, Florida, Fenqing Weng

USF Tampa Graduate Theses and Dissertations

The advance in remote sensing technology helps people more easily assess urban growth. In this study, the utility of multiple endmember spectral mixture analysis (MESMA) is examined in a sub-pixel analysis of Landsat Thematic Mapper (TM) imagery to map urban physical components in Tampa, FL. The three physical components of urban land cover (LC): impervious surface, vegetation and soil, were compared using the proposed MESMA with a traditional spectral mixture analysis (SMA). MESMA decomposes each pixel to address the heterogeneity of urban LC characteristic by allowing the number and types of endmembers to vary on a per pixel basis. This …
