“…As it can be seen in Table 1, their magnitudes were greater than 5 for two events (the first one near Kraljevo, and in the Tyrrhenian Sea) while other two had magnitude larger than 4. These magnitudes are larger than those related to other EQs considered in [33]. During the considered four time intervals, additional weaker EQs also occurred near the considered signal propagation path.…”

“…However, contrary to the previous cases this pioneer study which indicates a possible new ionospheric precursor of earthquake is provided only for the amplitude i.e., variations of the phase, is not considered. For this reason, in this study we extend the research presented in [33] and investigate if the recorded changes in amplitude noise are also visible in analysis of the VLF signal phase, and if excitations and attenuations of the acoustic and gravity waves can be visualized from the recorded phase. We show analysis of the phase of the ICV signal emitted in Italy and recorded in Serbia in periods around four EQs with magnitude greater than 4 which are connected with the noise amplitude reductions in study shown in [33].…”
