Improved structural models of the Earth and the knowledge about seismic wave propagation allow seismologists to study earthquake mechanisms. The earthquakes could most generally be divided to tectonic and volcanic. The far-field radiation of most tectonic earthquakes can be conveniently described with the so-called double-couple system of forces.
However, a full seismic moment tensor representation is more complete form of the mathematical representation of seismic sources, especially in non-tectonic environments. Of particular interest are seismic events with anomalous seismic radiation and puzzling focal mechanisms, such as volcanic earthquakes, mid-ocean ridge events or explosions.
Different computational methods are used to reveal statistically significant non-double-couple components of the moment tensor and model complex finite sources.
A student with maths and physics background and strong analytical skills is invited to join the project and assist with analysis and interpretation of results.
