Investigating of VLF signal precursors of earthquake near Sumatra Island / Nur Zulaikha Mohd Safuan

This paper investigates the possibility of earthquake precursors using narrowband Very Low Frequency (VLF) signal propagating in the earth ionosphere waveguide. VLF signals from VTX transmitter is used because its propagation path passes through the seismic active region in the Sumatra Island. Out o...
