3.0 Semester Hrs.Įquivalent with GPGN455, (I) Earthquakes are amongst the most significant natural hazards faced by mankind, with millions of fatalities forecast this century. 3 hours lecture 3 hours lab 4 semester hours. Prerequisites: GPGN404, GPGN329, GPGN314. The final exam consists of processing a 2D seismic line with oral presentation of the results. A three-hour lab introduces the student to hands-on data processing using Seismic Unix software package. Realistic synthetic examples and field data sets are extensively used throughout the course. Topics include data organization and domains, signal processing to enhance temporal and spatial resolution, identification and suppression of incoherent and coherent noise, velocity analysis, near-surface statics, datuming, normal- and dip-moveout corrections, common-midpoint stacking, principles and methods used for poststack and prestack time and depth imaging, migration velocity analysis and post-imaging enhancement techniques. 4.0 Semester Hrs.Įquivalent with GPGN452, (I) This course covers the basic processing steps required to create images of the earth using 2D and 3D reflection seismic data. Students will also cover the recent developments in 3D numerical earthquake source and wave propagation modelling as well as common & modern seismic data formats and processing/visualization tools and techniques used in earthquake seismology. This course provides an overview of how earthquake seismology, complemented by geodesy and tectonic geomorphology, can be used to determine earthquake locations, depths and mechanisms understand Earth's tectonics and rheology establish long-term earthquake histories and forecast future recurrence mitigate against seismic hazards illuminate large- and fine-scale features of Earth's interior using earthquake data. They are also our most accessible source of information on Earth's structure, rheology and tectonics, which are what ultimately govern the distribution of its natural resources. 3.0 Semester Hrs.Įquivalent with GPGN555, (I) Earthquakes are amongst the most significant natural hazards faced by mankind, with millions of fatalities forecast this century.
