Project description
VLF transmitters signals in the seismic regions - statistical studies
Many past researches describe anomalous behaviour in electromagnetic measurements, associated with seismic and volcanic activity. Some of these signals have been used in the studies of the possibility of the earthquake prediction, as pre and post seismic events that occur few hours or even few days before main shock. However, due to the subtle and poorly understood nature of earthquake precursors activity, it is necessary to examine as many data sets as possible, in order to gain more complete understanding of the physical mechanism involved in the precursors signal generations.
The main goal of our work is NOT predicting earthquakes, but analysing the emission, changes and abnormal behaviour of signal in the VLF range.
We do statistical studies on electromagnetic signals in VLF range.
If we know that we are looking for abnormal behaviour of VLF signal. First we must define what is normal. For this reason we need the reference signal. For the reference signal we use the signal from ground radio-navigational stations. Studying the evolution of such signal may provide an evidence of connection between changes in electromagnetic environment and seismicity.
Page structure
This page is divided into three important sections. First one, called Transmitters, contains the list of those transmitters that can be used as the reference transmitters. In this section you can also find information about signal intensity of recognized stations. In the second section, Signal Maps, you can find out, how the signal global maps were made. Finally, in the third part, called Seismic Events, you can find examples of studied seismic cases.
