This course offers a comprehensive exploration of seismology and earthquake engineering by delving into both theoretical foundations and practical applications. Learners will begin by examining the Earth's internal structure and the elastic rebound theory, gaining an understanding of seismic waves, their propagation, and velocity. The curriculum then expands into the dynamics of plate tectonics and active faults, detailing the processes that trigger earthquakes and their profound impacts on the built environment.A key component of the course is the analysis of strong-ground-motion measurement techniques using seismographs and accelerographs. Learners will learn to estimate essential ground motion parameters such as magnitude, frequency, duration, peak ground acceleration, peak ground velocity, and peak ground displacement. In addition, the course covers the computation of seismic moment, various magnitude scales, and the significance of epicentral distance.Advanced topics include the evaluation and application of attenuation equations to determine site-specific ground motion, as well as an in-depth study of soil-structure interaction-addressing issues like soil liquefaction and soil amplification during seismic events. Finally, the course focuses on assessing seismic hazards, risks, and loading on structures, offering strategies to mitigate seismic risk while reflecting on lessons learned from past earthquakes.This interdisciplinary program bridges geophysical principles and engineering practices, preparing learners for careers in seismic hazard assessment, risk reduction, and resilient structural design.
