Learning outcomes

After having followed the course the student is expected to be able to :

  • Account for the basic mechanism of fracturing in rocks.
  • Describe important models for the development of fractures in rocks.
  • Understand the dGPS technique and INSAR measurements and account for their measurement uncertainties.
  • Derive the relation between the seismic moment tensor and the deformation in a homogeneous medium.
  • Derive expression for the deformation around an edge dislocation in a homogeneous medium.
  • Determine source parameters from observations of deformations in the near field of an earthquake.
  • Determine source parameters for large earthquakes using broad band seismological observations, including the eigenoscillations of the Earth.

Content

  • Fracture mechanics applied to rocks.
  • Dynamic description of fracture development.
  • Represenation of earthquake sources using idealised point sources.
  • Green's functions for elastic waves.
  • Determination of parameters by means of near field data.
  • Determination of parameters for point sources by means of teleseismic data.
  • Measuring deformations on the Earth's surface by means of GPS and INSAR.
  • The relation between deformations on the Earth's surface and equivalent point sources.
  • Distributed sources and mathematical models thereof.
