  1. 1. Statistical Seismology Studies in Central America b-value, seismic hazard and seismic quiescence

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : David Aníbal Monterroso Juárez; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geophysics; b-value; seismic hazard; Monte Carlo; seismic quiescence; Central America; stress; Geofysik; NATURAL SCIENCES Physics Other physics Geophysics; NATURVETENSKAP Fysik Övrig fysik Geofysik;

    Abstract : The present thesis collects results of research applying theory and methods of statistical seismology to the seismicity of Central America, a region with a complex tectonic setting controlled by the interaction of four major plates, namely the Caribbean, Cocos, Nazca and North American plates.Three different earthquake catalogues were used for studies focused on stress in a tectonic volume, seismic hazard maps and seismicity patterns (precursors), covering the region 94ºW to 81ºW and 5ºN to 20ºN.

  2. 2. Earthquake Sources and Hazard in northern Central America

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Diego José Cáceres Calix; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Northern Central America; Probabilistic Seismic Hazard; Body waveform modeling; Seismic Active Deformation; Earthquake Triggering; Geofysik; NATURAL SCIENCES Physics Other physics Geophysics; NATURVETENSKAP Fysik Övrig fysik Geofysik;

    Abstract : Northern Central America is a tectonically complex zone defined by its borders with Cocos and North America plates. The Middle America subduction zone and the strike-slip motion along the North America-Caribbean plate boundary, in that order, control most of its deformation. READ MORE

  3. 3. Hydro-Climatic Variability and Change in Central America Supporting Risk Reduction Through Improved Analyses and Data

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Beatriz Quesada-Montano; Uppsala universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Central America; climate variability; disaster risk reduction; droughts; drought indices; floods; hydrological model; process constraints; statistical downscaling; uncertainty; ungauged basins; water resources.; Hydrology; Hydrologi;

    Abstract : Floods and droughts are frequent in Central America and cause large social, economic and environmental impacts. A crucial step in disaster risk reduction is to have a good understanding of the causing mechanisms of extreme events and their spatio-temporal characteristics. READ MORE

  4. 4. Observational Uncertainties in Water-Resources Modelling in Central America Methods for Uncertainty Estimation and Model Evaluation

    Abstract : Knowledge about spatial and temporal variability of hydrological processes is central for sustainable water-resources management, and such knowledge is created from observational data. Hydrologic models are necessary for prediction for time periods and areas lacking data, but are affected by observational uncertainties. READ MORE

    Abstract : Flooding is of great concern world-wide, causing damage to infrastructure, property and loss of life. Low-income countries, in particular, can be negatively affected by flood events due to their inherent vulnerabilities. Moreover, data to perform studies for flood risk management in low-income regions are often scarce or lacking sufficient quality. READ MORE
