Earthquake Geology:A tool for Seismic Hazard Assessment

Por: Swayam . en: ,

COURSE LAYOUT Week 1 : Crustal deformation and earthquakes (Seismicity), and its significance Plate Tectonics Week 2 : Signature of prehistoric earthquakes: Primary and Secondary signatures preserved in landforms and sediment succession Week 3 : Signature of prehistoric earthquakes (continued): Primary and Secondary signatures preserved in landforms and sediment succession Week 4 : Interpretation and Identification of Active Fault and associated Tectonic Landforms: Photogeologic Mapping, on-fault and off-fault landforms, identification and mapping of active faults and associated landforms. Week 5 : Interpretation and Identification of Active Fault and associated Tectonic Landforms (continued): Identification and mapping of active faults and associated landforms in different tectonic environments. Structural analysis of active faults & its implication to regional scale tectonics Week 6 : Field Techniques in Paleoseismology: Quantification of active fault scarp by precise mapping, identification of old (prehistoric) earthquake by trenching, mapping of deformed sedimentary succession by faulting. Week 7 : Field Techniques in Paleoseismology (continued): Estimation of net displacement during single event, slip rate, magnitude of historic earthquake, recurrence interval, and prediction of future earthquake if possible Week 8 : Identification and mapping of secondary effects: Secondary effects due to strong seismic shaking – identification of paleo-liquefaction features Dating Techniques: OSL and C14 Week 9 : Paleo-tsunami geology: Identification of Paleo-tsunami and Mega-subduction zone earthquakes signatures in the coastal region along subduction zones Week 10 : Paleo-tsunami geology (continued): Understanding land-level change caused by major earthquakes. Decoupling the role of climate and tectonics Week 11 : Paleo-tsunami geology (continued): Understanding the effect of near-field and far-field earthquakes from stratigraphic records. Effects of near-field and far-field tsunami Week 12 : Field Study: Identification and mapping of active faults and associated landforms in field.
