05-BGW-GD2 Seismology and Geomagnetism (bis SoSe 2025)

The seismology course conveys the theory of seismic wavefields to derive their properties and propagation through the layered Earth. The source parameters of earthquakes (hypocentre, magnitude and source mechanisms) will be determined from seismograms. Seismic catalogues will be used to analyse seismicity in different geological regimes.
The geomagnetism course first introduces discovery, phenomenology and usage of the geometry and temporal variation of the Earth´s magnetic field. We then develop a conceptual physical understanding of magnetohydrodynamic processes occuring in the Earth´s core, magnetosphere and ionosphere, in the sun and in the solar system.

1) comprehend and apply the properties and the propagation of seismic wave fields emitted by earthquakes
2) locate the hypocentre of an earthquake, calculate its magnitude, determine the focal mechanism and use earthquake catalogues
3) understand the complex physical conditions and processes from the core to the magnetosphere and solar system that generate and permanently vary the geomagnetic field
4) measure and calculate main field geometry, perform magnetostratigraphic dating, and analyze geodynamo model results and short-term field variations (space weather)
