EMSEV Potenza (Italy) 17-21 September 2018
Within the SAFE project, funded by ESA in 2015-2016  we have started to analyse possible effects in ionosphere of seismic activity, known as Lithosphere-Atmosphere-Ionosphere Coupling (LAIC) effects. During the project, we analysed 12 large and intermediate earthquakes showing that the use of Swarm data, integrated by ground observations (e.g. seismic and ionosonde measurements), is very important to better understand the preparatory phase of large earthquakes in the world. The positive results have convinced ESA to approve an extension (e-SAFE) of one year (presently ongoing and ending in 2019). The e-SAFE project, together with an ASI founded project, Limadou-Science, continues to show that there is a possible influence of lithospheric activity on the magnetic field and on the electron density measurements taken by Swarm satellites. In this presentation we will show some examples of anomalous magnetic and electron density Swarm tracks that precede some M6+ earthquakes  in the world and are potential seismic precursors of them. Finally we will show an automatic validation / correlation of the anomalies detected by Swarm satellites with the earthquakes occurrences showing some statistically significant concentrations of magnetic field and electron density anomalies that anticipate the earthquakes by around 85, 60, 20 and 10 days.
