A machine learning approach to investigate possible signals in the ionosphere related to earthquake activity

These results are based on analysis of magnetic field data measured by the three Swarm satellites during the first two years of the mission and the full earthquake catalogue from USGS. We applied some filtering to these data to exclude from the analysis the intervals characterized by stronger perturbations induced by the Sun, such as the ionosphere at high geomagnetic latitudes, and the periods with more intense geomagnetic activity.
