Low frequency signal spectrum analysis for strong earthquakes

Low frequency signal spectrum analysis for strong earthquakes

<p>We examined changes in the spectral composition of the low frequency (LF) subionospheric signals from the NRK transmitter (37.5 kHz) in Iceland that were received in Bari (Italy) relative to the earthquake that occurred in L’Aquila on April 6, 2009. In our previous studies, we have...
