Investigation of Changes in groundwater affected by the electromagnetic fields of the earth to predict earthquake

Studies show that earthquake causes chemical and physical changes in ground water. These changes can be recorded and used as geohydrologic precursors. Also according to recent research while earthquake and before, the waves of electromagnetic field of the earth vibrate, these vibrations are called magnetic anomalous. In earthquake knowledge, this type of anomalous is known as geohydrologic precursors. So the purpose of this research is to study the feasibility of the correlation between two precursors (geohydrologic and geomagnetic). In this study, to consider the effects of magnetic field on physical and chemical characteristics of water (i.e., electrical conductivity, total dissolved solids, and water level), a number of experiences have been done that can be used in short term and long term earthquake prediction. According to the results of statistical analysis, there is a meaningful partial correlation (confidence coefficient=95%) between magnetic field (geomagnetic precursors) and physical and chemical characteristics of water (geohydrologic precursors).
