ABSTRACT

The voluminous earth quake data sets, covering entire Northern part of India comprised of Himalayan Mountain belt is divided in to 3 parts i.e., North Western (NW), Central (C) and North Eastern (NE), and also the total data samples of entire Himalayan belt, constitute with Latitude, Longitude, Magnitude ( M ≥ 4 )  and Focal  depth(Lt, Ln, M, Fd) are considered for the present study. An attempt is made to analyze the relation between the 4 parameters Lt, Ln, M and Fd using the cluster and Factor analyses. The analyses of monthly resolution earthquake frequency time series suggest that earthquake processes in all three regions evolve on a high dimensional chaotic plane. The significant distinction in the earthquake dynamical patterns seems to be associated with the underlying seism tectonics of these three regions. 

Keywords: Multivariate Analysis, Cluster Analysis, Factor Analysis, Interactive Graphs.
