4-D Seismic Tomography for the Complex System of Strong Earthquakes: Formulation of a Problem

Chapter

Abstract

Geodynamic processes are acting in the Earth’s interior and they cause earthquakes of various intensity. Earthquakes occur randomly and they are often in clusters. Sometimes it happens that before strong earthquakes there is a seismic quiescence that is characterized by the absence of significant seismic events. This may indicate that Earth’s geological system prepares itself for a catastrophe. Complexity theory describes regularities of the behavior of dynamical systems before the occurrence of a disaster. The main part of this chapter is formulating a problem to investigate the behavior of a geophysical parameter, namely seismic velocity before the occurrence of the strong earthquake. Considering that velocity is a random variable, we apply the distribution function to estimate the dynamic state of the strong earthquakes complex system.
