Preliminary Non Linear Analysis of Seismic Events Associated with the Hydrothermal of Cangar, Batu, East Java

Abstract

About 25 seismic events in Cangar hot spring, Arjuno-Welirang Complex has been presented to identify its dynamic process. The delay time has been identified using autocorrelation and embedding dimension has been determined by selecting the False Nearest Neighbour equal to zero. Both of these parameters used to reconstructive the attractor diagram at phase space and to calculate the lyapunov exponent value. The results show the lyapunov exponent in study area are positive and they associated with the chaotic and deterministic system of hydrothermal area.
