Learning outcomes

After successful completion of the course, the student is expected to be able to:

• Describe important models for the development of fractures in rocks.
• Describe the dGPS 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 an expression for the deformation around an edge dislocation in a homogeneous medium.
• Determine source parameters from observations of deformation 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

Brittle fracture of rock, rock friction, mechanics of faulting, mechanics of earthquakes, the seismic cycle, 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.
