The general course outline covers the aspects of geology and seismology
which are relevant to the study and mitigation of seismic hazards. The
goal of the course is to provide the students with an understanding of
basic seismology and an introduction to the research that eventually leads
to seismic design code changes. For example the attenuation of seismic
energy with distance is a significant subject of GP130. Here students are
introduced to the concepts of geometrical spreading, anelastic attenuation,
scattering, empirical attenuation studies, and the influence of crustal
structure on the focusing and defocusing of seismic energy. Other topics
which receive considerable treatment in GP130 include, spectral analysis
methods, seismic source theory, elastic wave propagation and various case
histories of recent notable earthquakes such as the 1992 Landers, 1994
Northridge and 1995 Kobe events. Other topics that are covered in GP130
include:
