A method of hydrogeodynamical data analysis For revealing earthquake precursor

Abstract

In order to analyze data series, different methods of mathematical statistics are applied generally. However, all of them have one weak point: after removal of the trend caused by exogenous factors (tidal variation and atmospheric pressure) the applied frequency filters distort the required endogenous signal. We have developed a new method using computer program MatLab. It enables to synthesize a theoretical signal and compare it with original data of water level. The program enables to characterize each exogenous parameter separately. It allows studying the influence of each of them on the aquifer. It is determined that the aquifers are influenced by all kinds of exogenous factors. The reaction of boreholes demonstrates that one of them can dominate. After processing by suggested method almost identical figures describing the tectonic factor have been received.
