Course Description

Applied geophysical exploration technologies in disaster mitigation, civil engineering, and earth resources engineering is discussed in terms of seismological and of electromagnetic theories. Students may be asked to process data or design digital filters in the course.

Grading

Brief explanations on the grading will be given at the time of the lecture.

Course Goals

Understanding seismiclogical and electromagnetic theories used in geophysical exploration and subsurface-imaging technologies.

Course Topics

Theme Class number of times Description
Electromagnetic signal processing 3 Principles of magnetotelluric methods, electromagnetic sources and noise reduction.
Modeling technologies in electromagnetic methods 3 Subsurface structure modeling in EM methods. The effects of surface weathered layers, the identification of spatial dimensions, and modeling methodologies are discussed.
Signal processing in seismics 4 Digital filtering in seismic data processing.
Reflection seismology 3 Fundamental theories of reflection seismic data processing. Seismic migration is the one to be briefly discussed.
Petrophysics 2 Fundamental petrophysics, and fundamental measurement theories in geophysical logging are discussed.
