Learning Outcomes
Upon completion of the course, the students have understood the laws that govern the propagation of seismic waves inside the Earth (reflection, refraction, diffraction, amplitude and energy changes). For this purpose, the wave theory is used as well as elements of the theory of elasticity.
With these supplies, students will be able to recognize and distinguish phases in seismic recordings as well as understand and use waveform modeling software.
General Competences
- Retrieve, analyse and synthesise data and information, with the use of necessary technologies
- Work autonomously
- Work in teams
Course Content (Syllabus)
Wave propagation on a string: normal modes, reflection, transmission, energy of harmonic waves
Stress and strain
Principal stresses, equation of motion, constitutive equations
Seismic waves, plane and spherical waves, body waves
Snell's law, apparent velocity, ray parameter, slowness.
Reflection and transmission coefficients.
