ABSTRACT

The importance of understanding seismic waves and measurement waves has gravitated
form the seismic prediction to training electromagnetic propagation. Seismic electromagnetic waves may be useful in short-term earthquake prediction. It was found our observation system is influenced by lightning as far away as about hundreds km in the VLF and LF range. It is found that the increase in the number of LF and VLF electromagnetic pulses before earthquakes were generated by lightning. Some
researches show that there is some relationship between lightning and earthquakes. In this research, the continuous VLF electromagnetic waveforms were analyzed. Most of the waveforms were explained by lightning activities.
