The Routine Disaster: A Case Study In El Salvador, Tyler M. Barton
The Routine Disaster: A Case Study In El Salvador, Tyler M. Barton
Dissertations, Master's Theses and Master's Reports - Open
A 2010 report by the UN Disaster Assessment and Coordination ranked El Salvador as the most vulnerable country in the world to natural disasters, with roughly 95% of the population at risk. The combination of recurring natural disasters and high vulnerability in a relatively small country has led to repeated exposure of local residents to significant natural phenomena of all sorts, including earthquakes, flooding, landslides, volcanic eruptions, and hurricanes.
The effect of disaster assistance can be multi-faceted and this report examines the case of flooding hazards of a small town in the south-eastern San Miguel region of the country, called …
Tandem-X High Resolution Dems And Their Applications To Flow Modeling, Kelly M. Wooten
Tandem-X High Resolution Dems And Their Applications To Flow Modeling, Kelly M. Wooten
Dissertations, Master's Theses and Master's Reports - Open
Lava flow modeling can be a powerful tool in hazard assessments; however, the ability to produce accurate models is usually limited by a lack of high resolution, up-to-date Digital Elevation Models (DEMs). This is especially obvious in places such as Kilauea Volcano (Hawaii), where active lava flows frequently alter the terrain. In this study, we use a new technique to create high resolution DEMs on Kilauea using synthetic aperture radar (SAR) data from the TanDEM-X (TDX) satellite. We convert raw TDX SAR data into a geocoded DEM using GAMMA software [Werner et al., 2000]. This process can be completed in …
Characterizing The First Historic Eruption Of Nabro, Eritrea: Insights From Thermal And Uv Remote Sensing, Christine Ruth Sealing
Characterizing The First Historic Eruption Of Nabro, Eritrea: Insights From Thermal And Uv Remote Sensing, Christine Ruth Sealing
Dissertations, Master's Theses and Master's Reports - Open
June 2011 saw the first historic eruption of Nabro volcano, one of an ongoing sequence of eruptions in the Afar-Red Sea region since 2005. It halted air travel in northern Africa, contaminated food and water sources, and displaced thousands from their homes. Due to its remote location, little was known about this event in terms of the quantity of erupted products and the timing and mechanisms of their emplacement. Geographic isolation, previous quiescence and regional civil unrest meant that this volcano was effectively unmonitored at the time of eruption, and opportunities for field study are limited. Using free, publicly available …
