EARTHQUAKE PREDICATION TIME DOMAIN ANALYSIS SYSTEM FOR DECOMPOSING SEISMIC WAVE INTO TIME DOMAIN TO CAPTURE EARTHQUAKE PRECURSORY PHENOMENON

摘要

PROBLEM TO BE SOLVED: To predict the occurrence timing and place of an earthquake highly accurately, easily and quickly to estimate the magnitude of the earthquake, and provide seismic dynamics parameters for reflecting change in crustal dynamics throughout the course of an earthquake.;SOLUTION: The present invention develops a seismic wave decomposition technology. The present invention continues to observe change in a rock friction force coefficient and a crustal restoring force coefficient before seismic wave emission for a long period of time, and predicts the time and place of an earthquake by changing the correlation coefficient between the rock friction force coefficient and the crustal restoring force coefficient from positive to negative on the eve of the earthquake. Furthermore, the present invention estimates the magnitude of the earthquake by utilizing the strong positive correlation between initial change in the rock friction force coefficient and the crustal restoring force coefficient and a total seismic energy index. The seismic wave decomposition technique is a technique for performing crustal dynamics analysis using a non-linear self-returning summing process and decomposing seismic data into dynamics parameters by the least squares method.;SELECTED DRAWING: Figure 1
