   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistical Seismology; Earthquake Catalogue Statistics; Seismicity Patterns; Precursors; Foreshocks; Στατιστική Σεισμολογία; Κατάλογοι Σεισμών; Μοτίβα Σεισμικότητας; Πρόδρομα Φαινόμενα; Προσεισμοί; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

   Sammanfattning : Precursors related to seismicity patterns are probably the most promising phenomena for short-term earthquake forecasting, although it remains unclear if such forecasting is possible. Foreshock activity has often been recorded but its possible use as indicator of coming larger events is still debated due to the limited number of unambiguously observed foreshocks. LÄS MER

3. 2. Radar Probing of the Sun

   Författare :Mykola Khotyaintsev; Bo Thide'; Valentyn Mel'nyk; Christian Hanuise; Uppsala universitet; []
   Nyckelord :Space and plasma physics; solar radar; active experiments; space physics; solar corona; plasma; Rymd- och plasmafysik;

   Sammanfattning : This thesis is dedicated to the theory of solar radar experiments. The Sun exhibits a variety of interesting and complicated physical phenomena, examined mainly through analysis of its radiation. Active solar probing by radar provides an alternative possibility to study the Sun. LÄS MER
