Invention Title: Earthquake Early Warning System Based on Integration of Electrical Resistivity, Electromagnetic Field, Radon and Bioelectric Measurements

Abstract

SUMMARY OF INVENTION: This invention relates to a multi-sensor based earthquake early warning system and method that enables the detection of geophysical anomalies that may occur before an earthquake by evaluating electrical resistivity tomography (ERT), electromagnetic field (EMF) measurements, radon gas measurements, bioelectrical signal measurements, cosmic radiation measurements, and environmental meteorological parameters together. Within the scope of this invention, changes in electrical resistivity are measured via probe arrays placed underground, changes in electromagnetic fields in surface and near-surface areas are detected, differences in radon gas concentration are monitored, and changes in bioelectric potential occurring in living plant tissues are recorded. In addition, environmental effects are monitored through Geiger-Müller radiation sensors, atmospheric sensors, and high-sensitivity data acquisition modules within the system. The collected data is combined in a central processing unit and subjected to time synchronization, data filtering, correlation analysis, and anomaly evaluation algorithms. The system utilizes magnetrons, YIG oscillators, LNB-based receiver modules, and hexagonal coil arrays providing multi-directional sensing for electromagnetic signal generation and detection. Using the obtained results, the common behaviors of electromagnetic, geochemical, geoelectric, and biological changes that may occur in the pre-earthquake period are analyzed, and an anomaly index is created. Unlike measurement methods based on a single sensor, this system aims to reduce false alarm rates and more reliably identify anomaly signals that may occur before an earthquake by evaluating different physical parameters together. The data obtained can be shared between local or remote stations, mapped, and used to activate real-time early warning mechanisms. The invention encompasses a system and method that can be used in earthquake early warning systems, geophysical investigations, soil investigations, subsurface structure analyses, and multi-parameter environmental monitoring applications.
