Multidirectional analysis of the oscillating (T = 24 hours) Earth's electric field recorded on ground surface

TL;DR

This study analyzes the Earth's 24-hour oscillating electric field to identify its potential in seismic monitoring, demonstrating that electric field azimuths correlate with earthquake locations and can help estimate epicenters.

Contribution

Introduces a multidirectional analysis method of Earth's oscillating electric field to improve earthquake prediction and epicenter estimation using data from multiple monitoring sites.

Findings

Electric field azimuths align with earthquake locations

Method successfully estimates epicentral areas

Analysis shows potential for seismic forecasting

Abstract

The Earth's preseismic oscillating (T = 24h) electric field recorded for a short-time period of some days is analyzed in terms of its intensity vector azimuthal direction calculated at one monitoring site. The calculated azimuthal directions are compared to the concurrent seismicity observed for the same period of time. Examples are presented for proving the agreement between the electric field intensity vectors calculated azimuths and the corresponding ones referring to the EQs - monitoring site location. Finally, an example is presented on account of the use of this methodology upon three different monitoring sites for the utilization of the estimation of the epicentral area of a large future EQ at the Methoni, Greece seismogenic area.
