Strong natural hazards (NHs) have large social, economic and environmental impacts in several ways. Remote detection and classification of events is therefore an important task. In this study we investigate electric field variations in the sub-ionospheric waveguide between very low frequency/low frequency (VLF/LF) transmitters and the International Network for Frontier Research on Earthquake Precursors (INFREP) receiver facilities. The combined VLF/LF data sets enable to disentangle NH events from local, site-specific influences. Parallel to this long-term multi-station network in Europe we use complementary data sets, among them ionospheric satellite magnetic field measurements from ESA’s Swarm mission.  

We show the status of the INFREP network, discuss detection thresholds of the system related to NH events, and improvement potentials with the focus on different data processing methods.
