Geospatial Analyses Of Seismic Hazards And Risk Perception In Libya, Somaia Suwihli Jul 2020

Geospatial Analyses Of Seismic Hazards And Risk Perception In Libya, Somaia Suwihli

Graduate Theses and Dissertations

Libya is not considered a highly active seismic region. However, several earthquakes of magnitude >5.0 have occurred there. This dissertation analyzes the seismicity of Libya in order to better understand earthquake hazards, related geomorphic features, and the current evolution of Libyan perceptions of seismic risk. The first article developed a baseline of past and current seismic inventory in Libya, which represented an assessment of Libya seismic hazard by translating, analyzing, and compiling historical sources and archaeological data. This study shows that Libya has experienced earthquakes in varying degrees since ancient times. Through the spatial and temporal distribution of earthquakes from …


A Spatial Analysis Of Student Safety And Perception, University Of Arkansas-Fayetteville, Casey Goodman Jul 2020

A Spatial Analysis Of Student Safety And Perception, University Of Arkansas-Fayetteville, Casey Goodman

Graduate Theses and Dissertations

The objective of this research lies within a community's effects upon, reactions to, and perceptions towards safety in their inhabited landscapes during various periods of the day. Through cognitive and spatial research, we can construct bridges between individuals' perceptions and reality. This study pertained to a student population sample and their views of public safety on the University of Arkansas campus in Fayetteville, Arkansas. Questions were asked as to why they felt unsafe, and where they felt the most unsafe (or safe). The student perceptions were compared to reported crimes on the University of Arkansas campus to ascertain gaps in …


Far-Right Extremism In America: A Geospatial Analysis Of Incident Distribution, Meredith Leann Lerma Jul 2020

Far-Right Extremism In America: A Geospatial Analysis Of Incident Distribution, Meredith Leann Lerma

Graduate Theses and Dissertations

There has been little empirical research on the spatial relationship of violent far-right extremism. Previous studies have only focused on portions of far-right violent incidents, such as homicides, or amalgamated all far-right extremist activity, including legal incidents. This study uses data from the Extremist Crime Database (ECDB) and Southern Poverty Law Center (SPLC) in a temporal frame of 2000 to 2018 to test the relationship of violent incidents against geographic and social factors. The goal is to explore the relationships between macro-level factors and violent far-right extremist incident. The research determines that the presence of hate groups, higher immigrant populations, …


Landscapes Of Danger: A Geospatial Analysis Of Perceived And Realistic Risk In Bryce Canyon National Park, Tia Francis May 2020

Landscapes Of Danger: A Geospatial Analysis Of Perceived And Realistic Risk In Bryce Canyon National Park, Tia Francis

Graduate Theses and Dissertations

The quantification of risk has inspired a wide breath of literature from the physical sciences, social sciences, and interdisciplinary disciplines like geography. Many attempts to estimate risk via natural hazards either focus on quantifying realistic risk or perceived risk of lay persons, with very little overlap between these paradigms. Due to this, a considerable knowledge gap exists within perceived risk and natural hazards research. This study aims to provide a comprehensive, risk estimation and assessment strategy through a multi-hazard risk assessment of Bryce Canyon National Park (BRCA). This case study analyzed knowledge of risk among visitors with perception surveys and …
