Exploration Seismology (GEOL 5543/4543): Through a series of eight in-class exercises, this semester long course introduces students to the fundamentals controlled-source seismology. Upon completion, a student can a) sketch geometrically accurate reflection and refraction ray paths in a three-layered earth model and estimate the corresponding arrival times; b) use processes such as bandpass filtering and deconvolution to enhance signal-to-noise ratio of seismic data; and c) interpret basic structural features by mapping horizon and faults in a 3D seismic volume. The first third of the course includes ray tracing, fold calculation in a seismic profile and move-out analysis. The second third of the course includes 2D seismic processing modules such as time, frequency and wavenumber filtering, deconvolution, stacking and migration. The last part of the course focuses on basic seismic interpretation including horizon and fault mapping.

Earthquakes, Volcanoes and Other Natural Disasters: This online course introduces students to various kinds of natural disasters such as earthquakes, volcanoes, landslides, and flooding and the causative relation between human society and natural disasters. A series of lectures covers basics of fundamental geology, geological processes, how hazards play natural functions, and what human society can do to minimize the loss of life and property in the wake of natural hazards. The course addresses topics such as urbanization and climate change.
