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

    Författare :Diego José Cáceres Calix; Ota Kulhánek; Vladimir Schenk; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Northern Central America; Probabilistic Seismic Hazard; Body waveform modeling; Seismic Active Deformation; Earthquake Triggering; Geofysik; Geophysics; Geofysik;

    Sammanfattning : 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. LÄS MER

  3. 2. Statistical Seismology Studies in Central America : b-value, seismic hazard and seismic quiescence

    Författare :David Aníbal Monterroso Juárez; Ota Kulhánek; Stefan Wiemer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; b-value; seismic hazard; Monte Carlo; seismic quiescence; Central America; stress; Geofysik; Geophysics; Geofysik;

    Sammanfattning : 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.

  5. 4. Wintertime compound extremes in Europe and North America : from dynamics to predictability

    Författare :Richard Leeding; Gabriele Messori; Jacopo Riboldi; Deliang Chen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cold Spells; Climate Extremes; Extratropical Cyclones; North Atlantic; North America; Europe; Meteorologi; Meteorology;

    Sammanfattning : This thesis examines the co-occurrence of wintertime low temperature extremes (cold spells) over North America and wet or windy extremes over Europe. Prolonged (≅ 5 days) North American cold spells can be associated with both upstream and downstream anomalous large-scale atmospheric flows, the latter modulating extreme weather occurrences over Europe.

  7. 5. Ecology and Control of Triatomine (Hemiptera: Reduviidae) Vectors of Chagas Disease in Guatemala, Central America

    Författare :Maria Carlota Monroy; Thomas G.T. Jaenson; Chris Curtis; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Chagas disease; control; epidemiology; ecology; Triatoma dimidiata; T. nitida; T. ryckmani; Rhodnius prolixus; serology; populations movements; geographic distribution.; Biologi; Biology; Biologi;

    Sammanfattning : This thesis analyses several factors affecting the control of triatomines in Guatemala. There are three synantropic triatomines in Guatemala, i.e., Rhodnius prolixus, Triatoma dimidiata and T. LÄS MER
