Analysis of the Complexity of Seismic Data Sets

Abstract The investigation of the dynamics of complex seismic processes remains a major scientific challenge. Presently this problem is viewed in the light of modern concepts of the spatiotemporal behaviour of highly nonlinear or complex natural systems. The significant progress in this direction achieved over recent decades has paved a new avenue of research in the investigation of qualitative and quantitative aspects of the dynamics of seismic processes. Special attention has been paid to the elaboration of new methods of measuring the complexity of both global and local dynamics from seismic data sets. In this chapter, we present examples using several modern data analysis approaches on data sets related to seismic activity in the Caucasus. These data analysis methods are often used for the qualitative and quantitative evaluation of the complexity of natural processes, including seismic processes in different parts of globe.
