In collaboration with Ragnar Slunga, his most important contributions were in automatic estimation of fault-plane solutions for microearthquakes by inverting observed polarities and spectral amplitudes of P- and S-waves, and in relative locations of microearthquakes. Sigurður’s research thus demonstrated that microearthquakes contain information about large-scale tectonic processes.
During his student years

EA Analyse A/S and Optensys
Energianalys will forecast energy system variables, while SINTEF Energy Research will make
assumptions for the energy system in different cases, include new inputs in the EMPS model and
carry out simulations.
