Statistical Analysis of Natural Water Conductivity Data Behavior in Two Wells: Seismic Coastal Border Limits of Guerrero-Oaxaca States, Mexico

Abstract

In this document, with the purpose of strengthening more in the knowledge of the previous events on the earthquakes, the possible connection between natural voltage and electromagnetic energy emanating from the inner layers of the Earth and the seismic activity in the Mexican seismic coastal border, is evaluated, through an indirect estimation of the statistical analysis of natural water conductivity data (μS/cm) and the seismic activity occurred in the same period within continental and marine environment, monitored intensively from February 2 to April 15, 2015 and from May 11 to July 17, 2015 in two ordinary man-made wells. A total 128,469 water conductivity data with a sampling frequency of 45 seconds, confronted with 950 earthquakes occurred in the same periods to distance range of 50, 100, 150, 200, 250, 300, 350 and 400 kilometers far away from a conductivity sensor, are analyzed. As results, in the range of 50 kilometers round the conductivity sensor, the study area applied demonstrates to be a location where the major quantity of earthquakes and most atypical conductivity variations occurred. The influence of the local environment on the behavior of the conductivity data is debated according to the geographical position of the conductivity sensor. Within the continental environment, the range of 0 to 50 km showed the most important statistical significance, revealing to have the most number of earthquakes, with higher values and more intensity, particularly when the trend of conductivity data is descending. Within the marine environment, a very similar connection between the conductivity data behavior and seismic activity occurred was observed.
